Safety relay ESM-2H.. , type IIIc evaluation unit for two-hand control
- Use up to category 4 according to EN ISO 13849-1
- Requirement level IIIC according to EN ISO 13851
- LED status indicators
- Operation by 2-hand control
- 2 redundant safety contacts
- Short-circuit and earth fault/ground fault monitoring can be selected
Ismertetés
Relay outputs
The outputs are electrically decoupled and of redundant design.
Connection
- Two buttons, each with one normally closed contact and one normally open contact, that are monitored for simultaneity according to EN ISO 13851. In this way a high level of protection against tampering is provided.
- 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.
Connection options
By using suitable wiring the following function can be selected:
- Monitoring of downstream relays or contactors.
