Description
The PSR-...- 24DC/URD3/4X1/2X2/3 safety relay can be
used as a contact extension block in safety circuits
according to DIN EN 60204-1/VDE 0113-1.
The device has an interface for the T-BUS DIN rail
connector. This interface can be used for single-channel
control and monitoring. Alternatively, the device can also be
operated in single-channel mode via a contact on the basic
device.
Depending on the external wiring, up to safety category 3
according to EN 954-1 can be achieved.
The relay has four enabling current paths, one signaling
current path, and one confirmation path. Depending on the
time set, the contacts drop with a 0.3 ... 3 second delay
according to stop category 1 (DIN EN 60204-1/VDE 0113-1).
The extension unit can be used as a contact multiplier for
emergency stop relays and two-hand controls.
Observe the safety instructions on page 4.
