Safety relay for emergency stop and safety door

monitoring

PSR-MC20

Data sheet

Intended Use

The PSR-MC20 safety relay can be used to monitor single-

channel signal generators, e.g.,emergency stop buttons

and safety door locking mechanisms, and to control actua-

tors.

The safety relay is equipped with three enabling current

paths that drop out without delay corresponding to stop cat-

egory0 according to EN60204-1.

The enabling current paths are controlled as an automatic or

manual, monitored start once the sensor circuit has been

closed.

With the manual, monitored reset device, a machine start

may not be triggered in accordance with ENISO13849-1.

Features

– Safety relay for emergency stop and safety door moni-

toring

– Suitable up to category1, PLc (ENISO13849-1),

SILCL1(EN62061)

– Depending on the application, suitable up to catego-

ry4, PLe (ENISO13849-1), SILCL3(EN62061)

– 1 single-channel sensor circuit

– 3 undelayed enabling current paths

– 1 digital signal output

– Option of screw or spring-cage terminal blocks for plug-

– 12.5mm housing width

WARNING: Risk of electric shock
