INTERFACE
Data Sheet
102987_01_en
Description
The
PSR-...- 24DC/URD3/4X1/2X2/T2
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. The contacts drop
with at least a 2 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.

Safety Instructions
–
–
–
During operation, parts of electrical switching devices carry hazardous voltages.
Before working on the device, disconnect the power.
Please observe the safety regulations of electrical engineering and industrial safety and liability
associations.
Disregarding these safety regulations may result in death, serious personal injury or damage to
equipment.
Startup, assembly, modifications, and upgrades may only be carried out by a skilled electrical
engineer.
For emergency stop applications, the machine must be prevented from restarting automatically by
a higher-level control system.
Protective covers must not be removed when operating electrical switching devices.
In the event of an error, replace the device immediately.
Repairs, especially if the housing must be opened, may only be carried out by the manufacturer or
authorized persons. Otherwise the warranty is invalidated.
–

–
–
–
When operating relay modules, the operator must meet the requirements for noise emission for electrical and
electronic equipment (EN 61000-6-4) on the contact side and, if required, take appropriate measures.

Function
When the 24 V DC operating voltage is applied at terminal
blocks A1-A2 or is led via the DIN rail connector, the
"Power" LED lights up.
When a 24 V DC voltage is applied at input K1-K2 (or via
the DIN rail connector), both relays are activated. The LEDs
light up and the contacts for enabling current paths 27-28,
37-38, 47-48, and 57-58 close. Alarm contacts 15-16 and
65-66 open.
If the voltage is switched off at input K1-K2, the enable
contacts open and the alarm contacts close after two
second (2 s).
For additional connection examples, see page 7.
