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 574
- 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 a connecting cable 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.
