Phenix Contact Safety Relays PSR-SPP- 24UC/ESA2/4X1/1X2/B - 2963954

Description

Intended Use
The safety relay is used to monitor single-channel signal 
generators and to control actuators.
The safety relay interrupts circuits in a safety-related way.
Possible signal generators
– Emergency stop button
– Door locking mechanisms
Contact type
– 4 undelayed enabling current paths
– 1 undelayed enabling current path
The enabling current paths and the signaling current path 
drop out without delay according to stop category 0 
(EN 60204-1).
Control
– Single-Channel
– Automatic or manual start
A connected reset button is not monitored.
Achievable safety integrity
– Suitable up to category 1, PL c (EN ISO 13849-1), 
SILCL 1 (EN 62061)
– Depending on the application, suitable up to 
category 4, PL e (EN ISO 13849-1), 
SILCL 3 (EN 62061)
Additional features
– Safe isolation
– Option of screw or spring-cage terminal blocks for plugin

– 22.5 mm housing width
