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:
EXR10
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.
Technical data (25 °C)
l An additional protective element (circuit breaker or fuse) providing _{Voltage supply LINE+}
line or equipment protection in the event of a failure.

12/24 V DC
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.
