Electronic Relay with Extra Functions - EXR10 Description The electronic relay EXR10 (Electronic eXtra Relay) is a solid state relay combining various extra functions in a single unit. These include: l Solid state relay with diagnostic functions such as low voltage monitoring, wire break detection and current-proportional voltage output l Electronic overcurrent protection The relay fits into 4-pole or 7-pole standard automotive relay sockets to ISO 7588 (ISO Mini). It is suitable for system voltages of DC 12 V and DC 24 V (operating range DC 9...32 V) and can switch currents between 1 and 30 A. For remote switching and protection of loads, two separate components had up to now often to be connected in the load circuit as a functional unit: l An electro-mechanical relay or solid state relay which is powered via the control cable and then closes the circuit by means of the integral contact or power semi-conductor. l An additional protective element (circuit breaker or fuse) providing line or equipment protection in the event of a failure. The EXR10 combines diagnostic functions with overcurrent protection in a single component, thus minimising the number of connections in the circuit and reducing the failure risk. In addition the ETR10 is remotely resettable after overload tripping if an overload in the load path has caused the relay to switch off. Applications The EXR10 is suitable for all applications in DC 12 V and DC 24 V on-board electrical systems where magnetic valves, motors or lamps have to be switched and protected: l Road vehicles (passenger cars, bicycles, trucks, buses, working vehicles and emergency cars, special vehicles) l Construction vehicles and agricultural vehicles l Rail vehicles l Watercraft (ships, sailing boats, motor yachts etc.) l Industrial process control and production technology Features and Benefits l l l l l l l l Diagnostic functions regarding current, voltage or wiring can individually be adjusted to applications Plus-switching (positive control) solid state relay with high side switch (HSS) for load currents between 1 A and 30 A Integral protection against short circuit and overload in the load circuit Remotely resettable upon detection and disconnection of overcurrent by means of the protective function Silent switching Wear-free and robust design, insensitive to shock, vibration and dust (no mechanical contacts) Very low closed current and switching current consumption Fits into standard ISO Mini automotive relay sockets Approvals Authority Approval mark Regulation KBA E1 ECE R 10 1646 EXR10 Technical data (25 °C) Voltage supply LINE+ System voltage UB 12/24 V DC Operating voltage 9...32 V DC Closed current1)2) OFF 150 µA Load circuit LOAD Load outputMOSFET, high side switching (HSS) Load typesresistive, inductive and capacitive Protective functionshort circuit proof, overload protection temperature disconnection Current rating 3) IN 1...30 A Short circuit current IK max. 70 A (IN up to 10 A) L/R = 2ms 250 A (IN from 15 A) L/R = 2ms free-wheeling diode integral Voltage drop UON max. in mV (at IN in A) IN 1 2 3 5 7.5 10 15 20 25 30 UON 50 55 60 80 90 110 70 90 120 140 Control input IN+ Control voltage ON 8.5…32 V DC OFF 0…5 V DC Control current1)1…10 mA (8.5 … 32 V DC) Rising edge < 5 ms Status outputs (optional) Outputs S1 and S2 MOSFET low side switch (LSS) cont. current IS1,S2 max 500 mA Current-proportional U(I) 0...IN: 0...5 V ± 0,5 V output S3 > IN: 5...7 V PWM(I) 0...IN: 0...75 % ± 7,5 % > IN: 76...100 % 5 mA Cont. current IS3 max General data Reverse polarity control circuit yes protection load circuit no (due to free-wheeling diode) Switching times1) tON 4 ms tOFF 4 ms Temperature range -40° C to +85° C Degree of protection enclosure IP30 (not sealed) IP55 (sealed) Dimensions ISO Standard Mini plugged-in 30 × 30 × 40 mm incl. contacts 30 × 30 × 51.6 mm not sealed 25 g (IN up to 10 A) Mass1) 30 g (IN 15 A up to 20 A) sealed 75 g (IN 25 A or 30 A) 1) typically 2) with status outputs 300 µA 3) > 20 A only with high-quality or new sockets www.e-t-a.de 1 5 Electronic Relay with Extra Functions - EXR10 Order Technical data (25 °C) We require two parts of information for a complete order, the type number of the base unit (hardware) and the selected functions (configuration of software).
