ESM-CB-AZ-FI2-BR-IO-158875 (Order no. 158875)

Description

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 monitored start button
  • Monitoring of downstream relays or contactors
  • Simultaneity monitoring to monitor safety components over time
  • 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.

No time-delayed shutdown
