Contact expansion ESM-ES.., 3 safety contacts, 1 auxiliary contact, cat. 4
- Use up to category 4 according to EN ISO 13849-1
- LED status indicators
- Control using safety relays
- 3 redundant safety contacts
- 1 auxiliary contact (monitoring 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.
