Basic device ESM-BA2.., 2 safety contacts, cat. 4
- ESM-BA.. Use up to category 4 according to EN ISO 13849-1
- LED status indicators
- 1-channel or 2-channel control
- 2 redundant safety contacts
- Short circuit and earth fault/ground fault monitoring
- plug-in connection terminals
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 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 the connecting cables and earth or ground and to shut down the outputs or prevent relay starting if necessary.
Important:
Depending on the device in question, a connection kit will be required.
