IEC 62061
SILCL
Safety relay for contact extension
PSR-...-24UC/URM4/5X1/2X2/B
© PHOENIX CONTACT
Data sheet
Intended Use
The safety relay is used as a contact extension for safety
relays for the emergency stop and safety door monitoring.
The safety relay interrupts circuits in a safety-related way.
Possible signal generators
–Safety relays
Contact type
– 5 undelayed enabling current paths
– 1 undelayed confirmation current path
– 1 undelayed enabling current path
The enabling current paths, the confirmation current path,
and the signaling current path drop out without delay
according to stop category0 (EN60204-1).
Control
– Single or two channel
–Automatic start
Achievable safety integrity
– Suitable up to category4, PLe (ENISO13849-1),
SILCL3 (EN62061) in conjunction with an appropriate
evaluation device
Additional features
– Option of screw or spring-cage terminal blocks for plug-
in
– 22.5 mm housing width
