The electronic relay EXR10 (Electronic eXtra Relay) is a solid state relay combining various extra functions in a single unit. These include:
- Solid state relay with diagnostic functions such as low voltage monitoring, wire break detection and current-proportional voltage output
- 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:
- 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.
- 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
