Basic device ESM-BA3.., 3 safety contacts, 1 auxiliary contact, cat. 4
- ESM-BA.. Use up to category 4 according to EN ISO 13849-1
- LED status indicators
- 1-channel or 2-channel control
- 3 redundant safety contacts
- 1 auxiliary contact (monitoring contact)
- Short circuit and earth fault/ground fault monitoring
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.
Auxiliary contacts
The relays in the series ESM-BA3.. are available with electrically separate normally closed contacts and auxiliary contacts.
Connection terminals
Optionally, the ESM-BA… devices are also available as version with plug-in connection terminals.
