Ambient operating temperature [°C]
– 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.

Connection Notes
When using T-BUS DIN rail connectors, connect together the required number of T-BUS connectors and push them onto
the DIN rail. When attaching the safety relay to the DIN rail, ensure that it is aligned correctly with the T-BUS connector
(see Figure 4).
Figure 4 Using the T-BUS DIN rail connector
In order to comply with UL approval, use copper cables that are designed for operating temperatures > 75°C.
For reliable and safe-to-touch contacts, strip the cable ends as follows:
Figure 5 PSR-SCP- 24DC/URD3/4X1/2X2/T2 Figure 6 PSR-SPP- 24DC/URD3/4X1/2X2/T2
– Before working on the device, disconnect the power.
– For PSR applications, only yellow PSR-TBUS connectors (Order No. 2890425) may be used.
Connection with another T-BUS is not permitted.
– Devices may only be mounted on/removed from the T-BUS when the power is switched off.
– A T-BUS unit can contain a basic device (PSR-...-SDC...) and a maximum of 10 extension units
(PSR-...-UR...). Extension units must be mounted to the right of the basic device.
– The feedback circuit must be closed at the last extension unit (on the right): jumper at Y1 and 12
or PSR-TBUS-TP dummy plug (Order No. 2981716).
– The voltage supply can be provided at any PSR device or using a system power supply unit via the
T-BUS.
