Ismertetés

Relay outputs

The outputs are electrically decoupled and of redundant design.

Connection

By using suitable wiring the following function can be selected:

Earth fault/ground fault monitoring to detect short circuits between the connecting cables 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.
