Description
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.
