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

Supplies process-relevant parameters in real time
