RAD-ISM-2400-SET-UD-ANT RAD-Line IO – Unidirectional Wireless Transmission System INTERFACE Data Sheet 1 © PHOENIX CONTACT - 04/2006 Description The RAD-ISM-2400-SET-UD-ANT unidirectional radio system comprises a transmitter (Tx) and a receiver (Rx). The transmitter detects two digital signals in the range from 5 V AC/DC ... 30 V AC/DC, and one analog current signal (4 mA ... 20 mA). These signals are available for further processing at the receiver in the form of two relay PDT contacts and one 4 mA ... 20 mA current output. In addition, a third relay in the receiver diagnoses the status of the radio connection (RF link). The radio connection is established automatically when the operating voltage UB is applied to both devices. When the connection has been established, both RF LEDs are ON and the RF link relay in the receiver has picked up. From now on, a data transmission is started every 27 ms.

The control cabinet/box must meet the requirements of EN 60950-1 in terms of fire protection shielding. In the electrical system of the building, a two-pole disconnecting device must be provided to isolate the equipment from the supply circuit. In order to protect the modules against electrostatic discharge when working on control cabinets, the operating personnel must remove electrostatic discharge before opening control boxes or control cabinets and before touching the modules. Phoenix Contact hereby declares that the RAD-ISM-2400-SET-UD-ANT radio system complies with the basic requirements and other relevant regulations specified in directive 1999/5/EC. The radio system should only be operated using authorized accessories from Phoenix Contact. The use of other additional components may invalidate the device approval status. Applications in potentially explosive areas: The product meets the requirements for electrical equipment of Category 3G. The devices must be installed in housing that meets the requirements of IP54 according to EN 60529. Only passive antennas may be installed on the devices. The national safety standards and general technical regulations (e.g., EN 60079-14/VDE 0165-1), as well as general technical regulations, must be observed. 101511_03_en Installation Observe the assembly instructions for the antenna used. The antenna cable is plugged into the antenna female connectors 7/9. 6.2 Transmitter Display and Diagnostic Elements 4 5 6 LED: Digital input 1 = Status of digital input 1 Digital input 2 = Status of digital input 2 LED: RF link ON = Operating voltage UB present, transmitter is sending data Analog Input 2 The 4 mA ::: 20 mA analog input detects active and passive current sensors. For passive current sensors, the unregulated operating voltage UB is provided at terminal block 7. Digital Inputs 3 Both digital inputs on the transmitter can process voltages from 5 V AC/DC ::: 30 V AC/DC. They have a common ground potential (terminal block 11) and are electrically isolated from the operating voltage UB. PHOENIX CONTACT 6 RAD-Line IO UD 6.3 Analog Output (Also Operating Voltage) 1 Receiver Display and Diagnostic Elements 2 5 6 7 RSSI [V] 8 RF link relay The RF link relay in the receiver diagnoses the status of the radio connection. It picks up when the radio connection is established. If no data packets are received correctly over a period of approximately 3.4 seconds, the relay drops again. It picks up again automatically when the radio connection is re-established. The RF link relay has been designed as a PDT contact. LED: Digital output 1 = Status of digital output 1 LED: Digital output 2 = Status of digital output 2 LED: RF link OFF = No operating voltage UB; Flashes briefly approximately every 2 seconds = No reception; Flashes quickly = Connection is weak; ON: Radio connection established RSSI test socket A voltage measuring device (manual multimeter) can be connected to the RSSI test socket to measure a voltage, which provides information about the received radio signal. Using the diagram shown (Figure 4), the received signal strength in dB can be determined using the voltage value. This can be useful, e.g., when positioning and aligning the antenna. 5 4,5 4 3,5 3 2,5 2 1,5 1 0,5 0,75 0 -125 The analog output is supplied internally from the unregulated operating voltage UB. Terminal block 4 provides a power source at which the actuator to be connected is wired to ground (terminal block 5). The output requires an internal drop voltage of 10 V. The maximum load at the current output with a nominal voltage of 24 V = (24 V - 10 V)/ 20 mA = 700 Ω. The maximum load therefore depends on the operating voltage UB used. Digital Outputs 3/4 Two floating PDT contacts are used as the digital outputs for the receiver. 6.4 Behavior in the Event the Radio Connection Is Interrupted If the radio connection is interrupted, all outputs (analog and digital) retain their last value or status (see connection examples on page 8). To configure a reset response (revert back to "0") for a digital signal or the analog signal when a radio connection is interrupted, connect the RF link relay contact in series, for example. To configure a reset response for all signals, use the RF link relay to control one or more additional relays. 4,75 1 2 4,25 3 3,75 3,25 2,75 2,25 1,75 1,25 -115 -105 -95 -85 -75 -65 -55 -45 signal loss (-dB) Figure 4 RSSI diagram 1 = No connection 2 = Weak connection 3 = Good connection 101511_03_en → RF link LED flashes briefly approximately every 2 seconds → RF link LED flashes quickly → RF link LED ON PHOENIX CONTACT 7 RAD-Line IO UD 7 7.1 Connection Examples Transmitter Connection of a passive current sensor in 3-wire technology. +24V GND 6 5 4 RF 2 1 GND 7 8 9 4...20mA Power +24V 10 11 12 COM 5...30VAC/DC INPUT 2 INPUT 1 +24V Connection of a passive current sensor in 2-wire technology.

These voltages may cause compensating currents across the low-resistance path marked in red. Just a few volts can cause compensating currents in the range of several amperes, which may damage the device. Figure 5 shows the course of the compensating currents, which is created when different supply voltage sources are used for the sensor and the RAD-ISM-... device, and when the two sources have a separate ground reference. This arrangement (using different sources for sensor and RAD-ISM-... system) does not always cause problems. However, high compensating currents (in the range of several amperes) may cause damage to the device. To avoid these effects, the complete arrangement must only be grounded at one central point (e.g., not using the connection to PE2). 24 V DC 24 V DC GND GND Differential voltages between the potentials PE1 PE2 Internal connection with currentcompensating inductance Compensating currents POWER GND +24V OUT GND UB GND Internal connection RF 1 2 4 mA ... 20 mA sensor Output with external supply 4-20mA LOOP PWR IN GND DIGITAL IN 1 COM IN 2 101511A001 Figure 5 101511_03_en Avoiding ground loops PHOENIX CONTACT 10 RAD-Line IO UD 7.4 Installation in Potentially Explosive Areas With certification according to directive 94/9/EC (ATEX) and IECEx, the RAD-ISM-2400-SET-UD-ANT unidirectional radio system is a Category 3G, "n" explosion protection device, and can be used internationally in Zone 2 potentially explosive areas with hazardous gasses. Signals from outside the potentially explosive area as well as signals from Zone 2 can be directly connected. Signals from Zones 1 and 0 cannot be directly connected. They can only be connected via the appropriate barriers because the inputs are not intrinsically safe. Due to the limited transmission power the radio path itself may be led through Zone 1 and Zone 0. There are no restrictions.

The radio connection is established automatically – no other settings are required. Transmitter Receiver Point-to-Multi-Point In the point-to-multi-point system version, the set (RAD-ISM-2400-SET-UD-ANT, Order No. 2867283) is installed first, then the signals are connected, and the operating voltage is applied. The radio connection is established automatically. Signal paths can be divided or multiplied through the installation of additional receivers (RAD-ISM-2400-RX, Order No. 2867306). Transmitter 101511_03_en Receiver PHOENIX CONTACT 12 RAD-Line IO UD 7.6 Additional Receivers Any number of additional receivers (RAD-ISM-2400-RX, Order No. 2867306) can be used. The devices are supplied without a HOPKEY. The HOPKEY contains the transmission frequencies used and the hop sequence. This information is required when installing an additional receiver in an existing system. J10562 P001.1 To install an additional receiver, proceed as follows: 1. To protect the modules against ESD, the operating personnel must remove electrostatic discharge at appropriate points (e.g., control cabinet) before touching the modules. 2. The existing system must have established a radio connection. 3. Disconnect the power to the existing system. 4. Open the housing of the receiver in the existing system by pressing both housing latches on the sides. Remove the electronics module from the housing (see Figure 7). 5. At the bottom right on the PCB is a small PCB in a 10-pos. base – this is the HOPKEY. Remove the HOPKEY and insert it in the same position in the new receiver that you wish to install (see Figure 8). 6. Close all the housing covers and reinsert the modules in the control cabinet(s). 7. Reconnect the supply voltage – the additional receiver now receives the same information as the receiver in the existing system. 8. Repeat the procedure for all additional receivers. Explanation: When the supply voltage is connected, the information is transmitted from the connected HOPKEY to a non-volatile memory inside the module. This HOPKEY can then be used to "teach" other receivers. The HOPKEY can be stored in the last receiver. Figure 7 Removing the electronics module Figure 8 Removing and replugging the HOPKEY If no HOPKEY is connected, the information inside the module is used. J10562 P001.1 101511_03_en PHOENIX CONTACT 13 RAD-Line IO UD 8 Tips and Notes 9 8.1 Notes on the General Assignment of Frequencies – – In Gazette 22/1999, Order 154, the German regulating body for telecommunications and mail (RegTP) has stipulated a general assignment of frequencies. – Appendix EC declaration of conformity (see page 15) Declaration of conformity with health requirements (see page 16) Form to notify the RegTP of an installed radio path in/over a public area (see page 17) This general assignment applies to radio systems in the frequency range from 2.400 GHz ... 2.4835 GHz for general use. Section 10 specifies that the radio system operator has a duty to notify the RegTP in writing of the installation of a system, if it uses transmission paths that extend beyond the site. If, for example, another radio system is installed, which adversely affects an existing RAD-ISM system, then this system must adjust its operation if the existing system was already registered with the RegTP. System registration is therefore designed to protect the system operator. A form, which the system operator can use to notify the RegTP is provided in the Appendix. 8.2 Notes for Operating Other Radio Systems in Close Proximity If other radio transmission systems are operated on the same frequency close to an INTERFACE wireless system, interference may occur. The effects on the RAD-ISM-2400-SET-UD-ANT are marginal and barely noticeable. However, in certain circumstances an installed WLAN system (IEEE 802.11b) may be disturbed by frequency hopping, even if all specified maximum values are observed. To provide a solution for these cases, the RAD-ISM-2400-SET-UD-ANT reserves a small frequency range in the 2.4 GHz band. This is the range from 2.4220 GHz ... 2.4420 GHz, which corresponds to channel 5 of a WLAN system according to IEEE 802.11b. Should you experience the problem described above, please configure your WLAN system to channel 5. 101511_03_en PHOENIX CONTACT 14 RAD-Line IO UD 9.1 EC Declaration of Conformity 101511_03_en PHOENIX CONTACT 15 RAD-Line IO UD 9.2 Declaration of Conformity With Health Requirements 101511_03_en PHOENIX CONTACT 16 RAD-Line IO UD 9.3 Form to Notify the RegTP of an Installed Radio Path in/Over a Public Area Regulierungsbehörde für Telekommunikation und Post (Reg TP) Postfach 80 01 53105 Bonn Telefon 02 28/14-0 Fax 02 28/14-88 72 Informationen zu Funkanlage im 2,4GHz ISM Band Sehr geehrte Damen und Herren, hiermit setzen wir Sie über die Errichtung einer Funkanlage bei grundstücksüberschreitendem Übertragungsweg gemäss Amtsblatt 22/1999, Verfügung 154/1999, Punkt 10 in Kenntnis.
