Ismertetés

Relay outputs

The outputs are electrically decoupled and of redundant design.

Connection options

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

  • Relay start with automatic start or a start button.
  • Monitoring of downstream relays or contactors.
  • Simultaneity monitoring to monitor safety components over time.
  • Relay start using a monitored start button.
  • 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 a connecting cable and earth or ground and to shut down the outputs or prevent relay starting if necessary.

Auxiliary contacts

The relays in the series ESM-BA3.. are available with electrically separate normally closed contacts as auxiliary contacts.

Connection terminals

Optionally, the ESM-BA... devices are also available as versions with plug-in connection terminals.
