Electronic Relay with Timer Function – ETR10
Description
The smart power relay ETR10 (Electronic Timer Relay) is a remotely
controllable solid state timer relay and holds two functions in a single
device:
l Solid state relay with timer function
(time delay, pulsing, blinking)
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:
ETR10
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 ETR10 combines the timer relay function 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.
