Safety relays for monitoring non-equivalent signal

generators

PSR-MC50

Data sheet

Intended Use

The PSR-MC50 safety relay can be used to monitor two-

channel non-equivalent signal generators, e.g.,magnetic

switches, as well as to control actuators.

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 sensor circuit channel1 has

been closed and channel2 has been opened.

With the manual, monitored reset device, a machine start

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

Features

– Safety relays for monitoring non-equivalent signal gen-

erators, e.g.,magnetic switches

– Suitable up to category4, PLe (ENISO13849-1),

SILCL3 (EN62061)

– 1 two-channel non-equivalent 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
