ESM-2H201 (Order no. 085620)

Safety relay ESM-2H.. , type IIIc evaluation unit for two-hand control

The outputs are electrically decoupled and of redundant design.

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.
