ESM-2H201 (Order no. 085620)

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

Description

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.
