Contact expansion ESM-TE.., 3 safety contacts, 1 auxiliary contact, time-delay, cat. 3
- Use up to category 3 according to EN ISO 13849-1
- LED status indicators
- Control using safety relays
- 3 redundant time-delayed safety contacts
- Delay time range 1 s–30 s
- 1 auxiliary contact
- Earth fault/ground fault monitoring can be selected
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.
Time-delayed shutdown
The release time for the time-delay contacts can be set as required using a potentiometer on the safety relay.
