Data Sheet
102858_02_en
Description
The
PSR-...- 24DC/SDC4/2X1/B
safety relay can be used
in safety circuits according to DIN EN 60204-1/VDE 0113-1
and EN 954-1.
Control is implemented via single or two-channel switches
with N/O/N/C or N/C/N/C contacts (mechanical or elec-
tronic) or via light grids. The device has an interface for the
T-BUS DIN rail connector. This interface can be used for
single-channel control and monitoring of extension units.
For this function, a T-BUS connector with switchable con-
tacts is required.
Depending on the external wiring, the maximum safety cat-
egory that can be achieved is safety category 2 or 4.
The device has two enable current paths and a 24 V alarm
output (N/O contact function) with stop category 0 accord-
ing to EN 60204-1/VDE 0113-1.

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.
