exorbitant costs. As the standards covering low control voltages do not specify many parameters, the use of surge protection, apart from lightning protection zoning concepts, has to be classified according to type of signal, application circuit and the anticipated interference voltage phenomena. Types of interference voltage SU RG EP RO TEC TI ON Electrical system B ON SU RG EP RO TEC TI ON Lightning and surge protection for control and instrumentation signals Lightning and surge protection for control and instrumentation signals Basic classification The current scope of automation technology has resulted in a wide range of applications for surge protection in the field of instrumentation and control engineering. One important prerequisite is the consistent use of coordinated surge protection in all sections of the plant or building. In industry, instrumentation and control systems are important areas and Transient surges coupled into a system via one or more coupling mechanisms occur as normal- or common-mode interference. These are measured as longitudinal or transverse voltages and, depending on the circuit, designated as symmetrical or asymmetrical voltages.

(earth)/mainly caused by capacitive coupling (electrical field) B.6 Binary signals SL ≜ (symmetrical loop) These are two-wire signals with a common reference potential which are required by, for example, by switches, PLC switch outputs, photoelectric barriers, position sensors, solenoid valves, warning lamps, PLC inputs, etc. Normally, these signals have a common reference potential that can be either connected or not connected to earth potential, depending on the type of protection. The coupled transient interference is primarily common-mode interference. Analogue signals CL ≜ (current loop) common mode interference Upush-pull Types of signal Normal-mode interference (symmetrical interference): Normal-mode voltage between supply and return conductor load and interference source connected in series, e.g. inductive (magnetic field) or conductive coupling (common impedance) Measuring circuits are normally designed as two-wire current loops or voltage signals without a common reference potential, like the 0(4)...20 mA current loop. The coupled transient interference is primarily normal-mode interference. For temperature measurements with the PT100 measuring shunt in the three-wire version, the voltage drop at the shunt is measured via the third wire. This must be included in the system of protection. The PT100 measuring shunt is also available in a four-wire version in which the voltage drop at the shunt is measured via the two additional lines without additional line losses in the PT100 measuring circuit. The coupled transient normal-mode interference occurs between the various wires. 2028840000 Essential information for users can be found in the IEC 61643-22 standard (application standard for measurement and control signals) and in the IEC 62305-4 standard (application standard for installing internal lightning protection). It is important to determine which protection category is required. There are divisions for D1 (lightning protection), C2 (surge protection / overvoltage protection) and C1 (end device protection). These categories or classes are specified for the following products. All products were subjected to a test in accordance with product standard IEC 61643-21.

B Our pluggable VARITECTOR SPC surge protection is characterised by highest protective functions with compact dimensions. The arrestor of the modules can be removed, measured or exchanged during running operation impedance-neutral – without interrupting the measuring circuit. These features make this product the ideal secure protection mechanism for interfaces within instrumentation and control circuits. Maintenance intervals are simplified by the V-TEST test unit, which is used for testing the function of the VARITECTOR SPC. This test method satisfies the requirements of standard IEC 62305. With the VARITECTOR SPC R modules, error detection and error messages are realised by internal monitoring. The green LED indicates the active protective function. The red LED indicates a fault condition. This information is transmitted to the V-Control evaluation unit. From there, the information can be sent across to e.g. a controller. Due to the impedance-neutral removing of the arrestor, the VARITECTOR SPC modules can be used instead of terminals. For four binary signals or two analogue signals, just 17.8 mm of space on the mounting rail is used. By simply snapping onto a grounded mounting rail, time savings are also ensured when connecting. A colour code identifies the various voltage levels for all VARITECTOR SPC modules. This simplifies maintenance work during operation. The EMC set offers additional convenience for connecting shielded cables. All VARITECTOR products comply with the latest IEC 61643-21requirement for a new overstress mode. Space-saving Saves space in the switching cabinet: 4 binary signals or 2 analogue signals on 17.8 mm. B.8 Standard-conformant Usable in accordance with installations standard IEC 62305 safely discharges high impulse currents up to 20 kA (8/20 μs) and 2.5 kA (10/350 μs) to PE.

B.9 Lightning and surge protection for control and instrumentation signals VARITECTOR SPC B VARITECTOR SPC Pluggable surge protection for the measurement and control industry VARITECTOR SPC Weidmüller's VARITECTOR SPC pluggable surge protection is remarkable for its combination of extremely high protective functionality and compact dimensions. It is suited for use in measurement and control circuits. The size is made possible by the seletion of INSTA dimensions, with a width of 17.8 mm (1TE). Two versions are available: •VSPC: a surge protector with no monitoring function •VSPC R: a surge protector with monitoring function The base components are plugged in to form a direct earthing contact via the mounting rail. This saves you time when making the connection. The VARITECTOR SPC series is optimally designed for compact installations in process automation, industrial automation and building automation. The two-stage surge-protection base components are equipped with gas discharge tubes, suppressor diodes (TVS) and decoupling components. Individual protective components (such as gas-filled spark gaps, varistors and suppressor diodes) supplement this product line. IEC 62305 requires that a periodic inspection of surge protection products be conducted. The functionality of all VARITECTOR SPC modules can be tested using testing equipment (such as the V-TEST Basic) that is available separately. The VARITECTOR SPC R modules also feature an internal monitoring function. The green LED signals when the protection function is ready. The red LED signals an error. B.10 Up to ten modules can be wired together in succession. The modules alert an evaluative module (the VSPC CONTROL UNIT) in the event of an error. VARITECTOR SPC series surge protection is available with rated voltages of 5 V, 12 V, 24 V, 48 V and 60 V. The product's voltage level is colour-coded on the pluggable arrester. An earthing contact is established by snapping onto an earthed TS 35 rail. The TS 35 must be earthed in order to ensure safe power discharging via the terminals of up to 20 kA (8/20 μs) and 2.5 kA (10/350 μs). The rail must be screwed onto the earthed mounting plate for reasons of EMC. In order to optimise the protective function, a PE-contact connection should be made over the VSPC module every 60 cm for equipotential bonding. The pluggable protective element can be pulled out during operations without interrupting the measurement circuit. A testing instrument, available as a Weidmüller accessory, allows you to test the protective element in compliance with the IEC 62305-3 directive. The accessory also includes a simple mechanism for applying the wire shield. Overview of model types A VARITECTOR SPC (VSPC) consists of a pluggable component and a separate base component (VSPC BASE). Explanation of terms: CL = current loop / analogue signals SL = symmetric loop - for binary signals VSPC 2CL VSPC 2CL (CL = current loop) is a two-stage protective combination with a gas discharge tube and a suppressor diode located between the current paths. This VSPC 2CL limits the surge voltage within two analogue signal circuits (such as for current loops). This pluggable component can be inserted into the base (VSPC BASE 2CL). The base (VSPC BASE FG 2CL) is used when working with signal circuits which are not earthed. The VSPC 2CL HF is used in order to avoid influencing high-frequency signal circuits (this also includes the VSPC RS485 and the VSPC UK0). This protective combination is also inserted into the base mentioned above. Monitoring function The VSPC 2CL R products feature monitor and alert functions. As well as the alert function, there are two channels available for current loops in a single housing. The special VSPC BASE 2CL R and SPC BASE 2CL FG R bases 2028840000 Lightning and surge protection for control and instrumentation signals VARITECTOR SPC transfer the alert function to a 2-pole screw/plug-in connection in the bases and to the VSPC CONTROL UNIT. VSPC 1CL The VSPC 1CL is a two-stage protective combination with a gas discharge tube and a suppressor diode located between the current paths. This VSPC 1CL limits the surge voltage within one analogue signal circuit (such as for current loops). This pluggable component can be inserted into the base (VSPC BASE 1CL). The base (VSPC BASE FG 1CL) is used when working with signal circuits which are not earthed. Monitoring function The VSPC 1CL R products feature monitor and alert functions. All channels remain despite the alert function. The special VSPC BASE 1CL R and VSPC BASE 1CL FG R bases transfer the alert function to a 2-pole screw/plug-in connection in the bases and to the VSPC CONTROL UNIT. VSPC 4SL The VSPC 4SL is a two-stage protective combination with a gas discharge tube and a suppressor diode from the current path to the PE. This VSPC 4SL limits the surge voltage within four binary signal circuits (such as for alert contacts). This pluggable component can be inserted into the base (VSPC BASE 4SL). The base (VSPC BASE FG 4CL) is used 2028840000 when working with signal circuits which are not earthed. Monitoring function The VSPC 4SL R products feature monitor and alert functions. Even with the alert function, there are still channels available for the four binary signal circuits in a single housing. The special VSPC BASE 4SL R base transfers the alert function to a 2-pole screw/plug-in connection in the base and to the VSPC CONTROL UNIT. The VSPC 3/4WIRE is a two-stage protective combination with a gas discharge tube and a suppressor diode from the current path to the GND. This VSPC 3/4WIRE limits the surge voltage within four temperature-measurement circuits (such as for DMS or PT100/100 sensors). For non-earthed measurement circuits, we recommend using the base (VSPC BASE FG 4CL). B VSPC GDT VSPC 2SL The VSPC 2SL is a two-stage protective combination with a gas discharge tube and a suppressor diode from the current path to the PE. This VSPC 2SL limits the surge voltage within two binary signal circuits (such as for alert contacts). This pluggable component can be inserted into the base (VSPC BASE 2SL). The base (VSPC BASE 2CL FG) is used when working with signal circuits which are not earthed. VSPC MOV 2CH , VSPC TAZ 2CH and VSPC GDT 2CH Four cables can be protected with the 2CH modules. By wiring the connections differently, either two novoltage signal lines or four binary signal lines can be protected. Two three-pole gas discharge tubes (GDTs) are used for the VSPC GDT 2CH. This universal protective circuitry limits the voltage between the signal lines and also between each signal line and the PE. Monitoring function The VSPC 2SL R products feature monitor and alert functions. Even with the alert function, there are still channels available for the two binary signal circuits in a single housing. The special VSPC BASE 2SL R base transfers the alert function to a 2-pole screw/plug-in connection in the base and to the VSPC CONTROL UNIT. VSPC 3/4WIRE B.11 Lightning and surge protection for control and instrumentation signals VARITECTOR SPC Applications B VSPC TAZ VSPC MOV The VSPC MOV 2CH and TAZ 2CH offer one-stage protection with a varistor (MOV) or suppressor diode (TAZ or TVS) between the current paths. This makes it possible to protect a no-voltage (floating) signal circuit. Two binary signal circuits can also be protected if terminals 1 and 7 are assigned to GND / PE. These VSPC pluggable components are inserted into the base (VSPC BASE 2/4CH). The base (VSPC BASE 2/4CH FG) is used when working with signal circuits which are not earthed. 24 V VSPC 1CL PW VSPC 1CL PW (power and signal 1CL) offers combined protection that is suitable for the 24 V DC power supply and the current loops within a device. This VSPC protects sensors with an additional 24 V DC. B.12 VSPC RS422/485 The VSPC RS485 is a two-stage protective combination with a gas discharge tube and a suppressor diode located between the current paths. This VSPC RS485 limits the surge voltage within two high-frequency signal circuits. This pluggable component can be inserted into the base (VSPC BASE 2CL). The base (VSPC BASE FG 2CL) is used when working with signal circuits which are not earthed. Monitoring function The VSPC RS485 R product features monitoring and alert functions. Even with the alert function, there are still two channels available for current loops in a single housing. The special VSPC BASE 2CL R and VSPC BASE 2CL FG R bases transfer the alert function to a 2-pole screw/plug-in connection in the bases and to the VSPC CONTROL UNIT. Earthing unit and test plug The earthing unit can be used during installation to short out the connected wires to earth. The earthing unit is swapped out for a VSPC pluggable component before the initial commissioning. The test plug has 2.3-mm sockets. These sockets can be used by a meter to check the connected measurement circuit. The pluggable INSTA housing was created in compliance with DIN 43880. It consists of a lower section (the VSPC BASE) and a pluggable component (the VSPC). The VSPC BASE is made from black PA6.6 V0. The pluggable component is made from red PA6.6 V0. The temperature range is from -40 °C to + 70 °C. The VSPC series has been tested to comply with IEC 61643-21 04/2008 and EN 61643-21. Modules were tested with categories C1, C2 and C3: with quick-rising edges with up to 300 pulses. Category D1 describes high power testing (10/350 μs lightning protection), so that the VSPC can be used according to IEC 62305-4. The base and pluggable components are colour coded according to the voltage level. This makes installation easier. Colour coding The pluggable components transfer their coding to the base element when they are plugged in for the first time. The voltage levels are also labelled with coloured Dekafix markers applied to the VSPC pluggable component. This gives you a better overview within the electrical cabinet. Voltage level ≤ 12 V 24 V Binary 24 V Analogue 48 V ≥ 60 V Special function Colour green blue yellow red violet white 2028840000 Lightning and surge protection for control and instrumentation signals VARITECTOR SPC Test possibility / V-TEST Because the modules are pluggable, it is possible to test the VSPC visually or by using a V-TEST testing device. The VSPC can be easily tested; the user needs only to insert the VSPC pluggable component into the V-TEST. The result is then shown on the display. The VSPC R modules also feature an internal monitoring function for the arrester. An error is the displayed at the defective module. The VSPC CONTROL UNIT can then transfer an alert to the control room. Reoccurring tests / V-TEST Monitoring The IEC 62305-3 requires testing and maintenance for lightning protection systems. This includes the testing of the arresters used in the system. Class of protection I/II III/IV Interval for complete testing 2 years 4 years Installation Remote error diagnostics Interval for visual inspection 1 year 2 years Caution! These periodic inspections may be extended with stricter requirements pertaining to special applications or regions. VSPC R When the VSPC module labelled “R” is inserted into the corresponding “R” base component, it is then possible to use the outage alert function via a two-pole plug. This screw/plug-in connection has a clamping range from 0.5 to 1.5 mm². The wire stripping length is 6 to 6.5 mm. A screwdriver with a 2-mm blade width is used to turn the screw. The VSPC Rs are connected in succession to the VSPC CONTROL UNIT evaluative module. Up to ten VSPC Rs can be connected in succession to the VSPC CONTROL UNIT. The evaluative module is supplied with 24 V DC. It is then responsible for the switching and for the voltage supply to the VSPC modules. A no-voltage (floating) CO contact can then be used to alert in the event of an outage. The error on the module, with the LED changing colour from green to red. An automatic reset is carried out by the VSPC CONTROL UNIT within one minute after the failed VSPC pluggable component is replaced. The VSPC series is appropriate for protecting signal circuits. In order to achieve a complete protective strategy for the facility, the power feed must be protected against Type II surge voltages (for example, by using our VPU II series). For existing lightning protection facilities, Type I protection must be used (for example, by using our VPU I series). Type II protection (for example, our VPU II) is sufficient when there is no lightning protection in place. B Fusing The VSPC surge protection modules are designed so that they are decoupled between the individual protective stages. The following must be observed when providing fuse protection externally: • Max. rated current • Deratings curve • Type of installation •Application l ≤ 3 meter 14 11 12 X1 X2 X1 X2 X1 X2 X1 X2 2 4 6 2 4 6 2 4 8 10 12 8 10 12 8 10 12 6 VSPC CONTROL UNIT VSPC .... ............R VSPC .... ............R U C : ..........

It is therefore necessary that C&I devices be protected in their immediate vicinity. For this purpose, VARITECTOR SSC, with its compact terminal-block format, is ideal for this application. The protective circuits are matched to the current loops and to binary signals. The VARITECTOR SSC products are tested according to the latest standards (IEC61643-21): They satisfy the safe short-circuit mode in the event of overload by AC currents in classes D1, C2 and C1. The products are ATEX-tested for use in intrinsically safe circuits. Easy to use The clamping area of 0.5 mm² – 6 mm² is covered with combined Torx®/Slot headed screw and a tightening torque of 0.8 Nm. Space-saving Modular width of terminals just 6.2 mm for two binary signals or per analogue signal.

The Omega stainless steel spring used for DIN rail contact ensures outstanding discharging characteristics that are consistent and reliable. Space-saving The narrow 6-mm MCZ OVP surge protector is installed simply and quickly due to its terminal block design. Quick to connect Maintenance-free tension-clamp wire connection: providing strong contact force and quick wiring times. This ensures a more securely clamped wire across the entire clamping area. B.108 2028840000 Lightning and surge protection for control and instrumentation signals MCZ OVP series Vibration-resistant PE contact Up to 10 kA (8/20 μs) of surge voltage can be reliably discharged via the stainless steel Omega spring. This contact snaps onto the rail and requires no tools to install. B High transfer rates with protection Variants are available for protecting data lines (including the following industrial bus systems: PROFIBUS, PROFINET, Interbus, C-Bus, MODBUS, LON™, CAN, DeviceNet, etc.) 2028840000 B.109 Lightning and surge protection for control and instrumentation signals MCZ OVP series B B.110 Narrow surge protection terminals with tension-clamp wire connections for measurement and control systems Weidmüller MCZ surge protection terminals are characterised by their maximum protective function, and a compact design of only 6 mm. The tension spring connection and direct earthing via the terminal rail contact results in time-savings during installation. The MCZ OVP terminals are suitable for installing in the tightest of places in automated process, industrial and building services systems. The different models The three-stage surge protection terminals are fitted with gas discharge tubes, varistors, suppression diodes (TAZ) and decoupling inductors. Individual protective components such as varistors and suppression diodes complement the range. The MCZ OVP surge protection terminals are available with rated voltages of 24, 48, 115 and 230 V. The response time for the 3-stage MCZ OVP is typically 100 ps. The earth contact is produced by clipping the terminal to an earthed terminal rail. To guarantee a safe energy discharge of up to 10 kA (8/20 µs) via these terminals, the TS 35 rail must be earthed. EMC regulations require the terminal rail to be securely screwed to an earthed mounting plate. Optimum protection is achieved when the PE contact is made via a tension spring terminal every 600 mm. Attenuation chart MCZ OVP Filter MCZ OVP HF is a two-stage protective combination with a bridge circuit consisting of suppressor diodes. With this circuitry, high transmission rates of up to 100 Mhz can be reached in 100 Ohm systems. The protective circuitry is particularly suitable for protecting high-speed data transmission systems and high-speed analogue systems. MCZ OVP CL is a three-stage protective combination with a suppression diode between the current paths. It limits the surge in analogue signal circuits, e.g. current loops. MCZ OVP SL is a three-stage protective combination with two suppression diodes, each from the signal line to earth. It limits the surge in binary circuits, e.g. for actuators. MCZ OVP CL FG is a three-stage protective combination with a suppression diode between the current paths. It limits the surge in analogue signal circuits. A high-resistance earth connection is achieved with a gas discharge tube. MCZ-OVP Filter-Terminals contain selected varistors, capacitors and series inductances. They form reliable noise filters. Coupled interference in the kHz range is safely discharged to earth. For example, the signal inputs of a PLC, which can be protected against interference voltages and RF interference. dB 50 40 30 20 10 0 -10 10K 100K 50 Ohms Insertion loss 1M Hz 10M 100M 200M Differential Mode (symmetrical) 2028840000 Lightning and surge protection for control and instrumentation signals MCZ OVP series MCZ OVP SL FG is a three-stage protective combination with two suppression diodes, each from the signal line to earth.

The earth is installed primarily to protect human life and for this reason is referred to as the protective earth conductor. On the other hand, shielding is used to ensure that the electrical system functions properly. It also ensures electromagnetic compatibility. The illustration below shows how these two topics relate to each other in application. These main differences between the two terms influence the electrical design and installation. Shielding is not designed to transfer power, although leakage currents may flow on them. A protective earth conductor, however, must be able to briefly discharge a high fault current (IEC 60947-7-2). The short-term current resistance of the PE connection must be 120 A/mm² for the connected cross-section. Different symbols are also used for the two themes: As shown in the picture below, the cable’s shielding is connected to the earth potential so that the shield’s current can be discharged. Depending on the sensitivity of the facility, isolated areas of potential can be created. However it is still typical to mix the areas, so that the shielding is on a common equipotential earth. This illustration shows how the number of shields and PE conductors that need to be connected can increase quite rapidly (in this case only one component is used). The shielding and earthing systems must be planned carefully to provide adequate safeguards for personnel and equipment. The following sections describe the complexity and uniqueness in more detail.

Electrical interference is introduced into circuits in many different ways. The most frequent cause is inductive interference effects. However, conductive or capacitive coupling plus electrical fields and other phenomena can also cause interference voltages. In these cases high-frequency voltage oscillations – the so-called transients – are very likely the cause of the interference. Shielded lines enhance interference immunity The sources of interference voltages can never be eliminated completely. Therefore, we have to take measures to deal with their effects. Generally, it is true to say that the more effectively we can keep interference voltages away or discharge them from circuit elements, the smaller are their disturbing effects. This can be done in many ways – with differing degrees of effectiveness. One really effective measure for protecting against inductive influences, i.e. guaranteeing the electromagnetic compatibility, is to shield the electric functional components at earth potential. One way of doing this is to install components in metal, earthed housings and to shield the connecting lines. Generally, it is true to say that counteracting the interference effects of lines is feasible by laying the lines as far apart as possible, keeping the common return as short as practical, or using twisted lines. A far better method of protection, however, is to provide a continuous shield for all lines. This is the most effective measure that can be taken against the coupling together of interferences. 2028840000 The best form of shielding consists of a braided hose of individual wires made from a non-magnetic material (copper, aluminium). The braiding should be sufficiently robust and as solid as possible. Care must be taken with lines protected by a foil shield because of the foil’s low mechanical strength and low current-carrying capacity. B Correct use of shielded lines Adding shielding to lines achieves the desired effect only when they are properly designed and installed. Incorrect earthing or the use of components that do not function satisfactorily reduce the effect or even nullify it altogether. It is not sufficient to connect the shielding to earth potential at just any point b ecause it could be the case that this earth connection is inadequate for high frequencies. In addition, we must also watch out for earth loops, the shielding must be earthed over a large area, and the quality of the shield bonding lines and earthing accessories is also important. B.121 Lightning and surge protection for control and instrumentation signals Earthing for shielded cables B Shielding In practice, the shield is often twisted and connected to a terminal point. There is very high attenuation (voltage drop) on these connections, especially for high-frequency interference. Therefore this type of shielding should not be used, even for short cable lengths. The cable shield is practically negated and can, at best, be helpful for lowfrequency interference. We recommend a large, extensive contact with the braided shield of the cable. The following pictures show examples of use: There are four main types of coupling: • Galvanic coupling • Capacitive coupling • Inductive coupling • Radiation coupling Such interferences usually occur mixed together, but they can be categorised as follows: • Electromagnetic fields • Ripple voltage (50 Hz) •Lightning • Interference pulses (current, voltage) • Transient surge voltages • Radio interference • ESD (electrostatic) •Burst • Mains feedback Shield connection via functional earth The conductor “flow” is another detail for concern with the shield contact. The temperature changes caused by the current flow lead to changes in the wire’s diameter. A rigid contact can therefore only be partially effective. A selfadjusting contact is what is really required. Weidmüller’s clamping yoke products (KLBÜ) provide the perfect solution for this challenge. Shield connection on common earth B.122 2028840000 Lightning and surge protection for control and instrumentation signals Earthing for shielded cables Effective shielding It is important to remember that the shielding should not be connected to the earth of the module connected, but rather to the protective earth (PE). In the case of modules mounted in an earthed, metal housing, the shielding must be connected to this housing. If an earthed housing is not available, the shielding must be connected to a separate earth. When laying earth connections to shields it must also always be ensured that no earth loops are formed. The smaller the earth loop, the lower is the risk of inducing interference voltages. Therefore, a true star arrangement is the best answer. The sketches below show general, feasible connections between shield and protective earth. Connecting the shield at one end protects against capacitive-coupled interference voltages. System 1 System 2 Connecting the shield at both ends is suitable for protecting against inductive-coupled interference fields. System 1 2028840000 A high-resistance connection at one end of the shield is recommended when trying to avoid the disadvantages of forming an earth loop in the case of shields connected at both ends. System 1 B System 2 On longer shielded lines, e.g. when a sensor has to be routed to the control room, the potential difference between the two ends should not be ignored. If a current-carrying shield bonding line is used, it is possible to compensate for the potential difference between the measuring point and the control room by means of this shield. However, such shield lines are relatively expensive and also complicated to fabricate and install. Another possibility is to lay an additional equipotential bonding line between the measuring point and the control room. The shield can then be connected at both ends. Yet another possibility is a high-resistance earth. The shield is then connected to earth potential in the control room, and at the measuring point connected to earth via a gas discharge tube in a high-resistance arrangement. This solves the problems of potential transfer and a 50 Hz hum. Two gas discharge tubes must be installed for non-floating measuring points. One connects the shield to earth and the other to the non-floating measuring point. This prevents conductive coupling between the measuring circuit and the earthed measuring point. Shield connector 1 4 5 Earth Measuring point TS 2 IN 3 OUT Summary The earthing is an important factor affecting the reliable operation of electrical installations in the event of interference effects. RF aspects must be taken into account. Only the correct use of materials and well-thought-out circuit design can bring success. System 2 B.123 Lightning and surge protection for control and instrumentation signals Installation advice for instrumentation and control engineering B Installation advice for instrumentation and control engineering The supply and earth lines to protective modules should be kept short in order to achieve optimum protection for equipment. The fuses for the protective modules should be chosen depending on the rated current as well as on the type of line and its route. Mounting rail contact as earth in connection for MCZ OVP Installation position The shielded signal lines should be connected to PE via terminal clamps (Weidmüller KLBÜ). Unshielded lines should be twisted. Neutral earthing is preferred. All the protective modules belonging to one part of the system should have neutral e arthing. A through-connection of the earth line should be avoided. Protected and unprotected lines must be laid separately. A common cable duct should be connected with metal partitions. Likewise, signal and power lines should be laid separately. Electrical isolation, e.g. with relay couplers or analogue converters, should be employed for installations involving several buildings. This avoids interference currents via minus, PE or N. The supply and earth lines to protective modules should be kept short in order to achieve optimum protection for equipment. Transmission paths should also be kept as short as possible because the longer the line, the greater is the chance that interference can affect the line. The inclusion of surge protection also increases the attenuation of the line and t herefore changes the signal-to-noise ratio. The protective modules are frequently installed at both ends of the line. It is important to ensure that protected and unprotected lines are routed separately. In addition, there must be some distance between power lines and data lines. A common cable duct should be connected with metal partitions. The protective modules should be mounted in a panel near the entry point of the lines. Unprotected lines should not be fed into parts of the system. Therefore, the lower level in the panel should be used for the protective modules. B.124 Contact to the rail is automatically established using the snap-on attachment. The TS35 rail must be earthed in order to ensure safe power discharging via the surge protection elements of up to 20 kA (8/20 µs) and 2.5 kA (10/350 µs). The DIN rail should be screwed onto the earthed mounting plate to ensure EMC. It is also possible to contact the PE every 60 cm / 24 inch using the tension-clamp terminal on the MCZ OVP. 2028840000 Lightning and surge protection for control and instrumentation signals Installation advice for instrumentation and control engineering Surge protection for binary signals The earthed DIN rail can then pick up the pulse and discharge it to the earth.

In these circuits, the intrinsically safe signal converters with their galvanic isolation and Ex approved surge arresters provide excellent protection for sensitive control electronics. Surge voltages on the field side of the measurement and control lines can damage the facility. The VARITECTOR SPC EX can discharge surge voltages in hazardous area applications (zone 0, 1 and 2). The pluggable arresters conform to the requirements of the current standards with regards to Ex intrinsic safety. They also comply with the IEC 61643-21 surge protection product standard and are certified for protection classes D1, C2 and C3. The ACT20X-HUI-SAO-LP offers an intrinsically safe input for standard DC signals, temperature signals and resistance signals. It also isolates the Ex zone from the safe area. The 12.5 mm wide module is powered via the 4 … 20 mA output. The global ATEX, IECEx and cULus Ex approvals allow it to be used throughout the world. Space saving The VSPC EX uses less space in the electrical cabinet, with four binary or two analogue signals in only 17.8 mm width.

B.133 Lightning and surge protection for control and instrumentation signals VARITECTOR SPC EX VARITECTOR SPC EX Pluggable surge protection for measurement and control systems B VARITECTOR SPC EX Weidmüller’s VARITECTOR SPC EX pluggable surge protector is remarkable for its combination of extremely high protective functionality and compact dimensions. It protects intrinsically safe measurement and control circuits. The size is made possible by the selection of INSTA dimensions, with a width of 17.8 mm (1 TE). You save time on connections because of the screw connection and the indirect earthing contact via the DIN rail. The VARITECTOR SPC series is optimally designed for compact installations in process automation, industrial automation and building automation. The two-stage surge protection terminals are equipped with gas discharge tubes, suppressor diodes (TVS) and decoupling components. IEC 62305 requires that a periodic inspection of surge protection products be conducted. The functionality of all VARITECTOR SPC modules can be tested using testing equipment (such as the V-TEST) that is available separately. You can get our VARITECTOR SPC surge protection series in the nominal voltages of 5 V, 12 V and 24 V. The product’s voltage level is colour-coded on the pluggable arrester. It can be snapped on an earthed DIN for indirect earthing. The TS 35 must be earthed in order to ensure safe power discharging via the terminals of up to 20 kA (8/20 µs) and 2.5 kA (10/350 µs). The DIN rail must be screwed onto the earthed mounting plate to ensure EMC. In order to optimise the protective function, the PE contact should be made every 60 cm / 24 inch using the terminal on the VARITECTOR SPC module. A testing device, available as a Weidmüller accessory, allows you to test the protective element in compliance with the IEC 62305-3 directive. Accessories also include the EMC SET which provides a simple method for creating the cable shield. Overview of model types Surge protection consists of a separate plug-in VARITECTOR SPC EX and a separate base unit VARITECTOR SPC BASE.

Class of protection I II III/IV Interval for complete testing 2 years 4 years 6 years Interval for visual inspection 1 year 2 years 3 years B Caution! These periodic inspections may be extended with stricter requirements pertaining to special applications or regions. Markers The VSPC BASE lower section can be labelled with Dekafix 5 markers. The VSPC pluggable modules are colour coded with Dekafix 5 according to their nominal voltage. Installation The VSPC EX series is used to protect signal circuits. In order to achieve a complete protective strategy for the facility, the power feed must be protected with Type II surge protection (for example, by using the VPU II series). For existing lightning protection facilities, Type I protection must be used (for example, by using the VPU I series). When there is no lightning protection system, the Type II protection is sufficient (such as the VPU II). Monitoring IEC 62305-3 requires testing and maintenance for lightning protection systems.

Lightning and surge voltages – whether direct at the facilities, near field or far field – can cause signal interference or even destroy connected devices. They could even lead to an explosion within hazardous areas applications. The VARITECTOR SSC EX product line, with a width of 12.4 mm, offers protection against these risks. These products comply with the new IEC 61643-21 standard. They fulfil the “overstress mode” described. They are also in compliance with the most current ATEX Standard, in EN 60079. Lightning and surge protection components are versatile and simple to use since they feature direct contact to the PE, many marking and diagnostic options, and an easily disconnected signal path. The VARITECTOR SSC EX takes advantages of these features so that it can easily be used in place of a transfer terminal. Space-saving A compact installation is possible because of the VSSC EX module's terminal design and 12.4 mm alignment width. No limitations when used in the EX zone The EX zone approval provides the proof that the VSSC EX can be used in all EX zones (from zone 2 to zone 0) for dust or gas.

B Complete, standard compliant protection The VSSC EX prevents compensation currents ia the PE. It also complies with the over stress mode of the IEC 61643-21 standard. No proof of intrinsic safety Because of the negligible Li and Ci values, no special proof is required for EX zone use.

Lightning and surge voltages – coupled from the field side to machines and facilities – can cause signal interference or even destroy connected devices. They could even lead to an explosion within high-risk Ex-zone applications. The new VARITECTOR SSC EX product line, with a width of 12.4 mm, offers protection against these risks. These products comply with the new IEC 61643-21:2008 standard. They fulfil the “over-stress mode” described. They also meet the latest ATEX standards, EN 60079. These lightning and surge components are a versatile and efficient solution because they feature a direct PE contact, extensive labelling and diagnostic options, and easy separation of the signal paths.
