ESM-2H201 (Order no. 085620)

Description

Relay outputs

The outputs are electrically decoupled and of redundant design.

Connection

  • Two pushbuttons each with one NC contact and one NO contact that are monitored for simultaneity according to EN ISO 13851. In this way a high level of protection against tampering is provided.
  • Short circuit monitoring to detect short circuits between the connecting cables and to shut down the outputs or prevent relay starting if necessary
  • 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.

Connection options

By using suitable wiring the following function can be selected:

  • Monitoring of downstream relays or contactors.
