ESM-TE301 (Rend. sz. 085617)


Relay outputs

The outputs are electrically decoupled and of redundant design.


By using suitable wiring, the following function can be selected:

  • Earth fault/ground fault monitoring to detect short circuits between a connecting cable and earth or ground and to shut down the outputs or prevent relay starting if necessary.

Time-delayed shutdown

The release time for the time-delay contacts can be set as required using a potentiometer on the safety relay.
