Data sheet
The PSR-...-24DC/ESD/5X1/1X2/300 safety relay can be
used for emergency stop, safety door and light grid monitor-
ing in safety circuits according to EN60204-1.
Depending on the external wiring, up to category 4, PLe ac-
cording to ENISO13849-1 or SILCL3 according to
EN62061 can be achieved for the undelayed contacts and
category3, PLd according to ENISO13849-1 or SILCL2
can be achieved for the dropout delayed contacts.
Control is via a single channel or two channels, either with
automatic or manual start circuit.
A connected reset button is monitored.
The safety relay is equipped with three enabling current
paths and one signaling current path that drop out without
delay according to stop category0.
Two other enabling current paths drop out with a delay in
compliance with stop category 1.
The delay time is set in 24increments via the rotary switch
and the DIP switch in the upper housing part.

7 Safety notes
WARNING: Risk of electric shock
During operation, parts of electrical switching
devices carry hazardous voltages.
Before working on the switching device, dis-
connect the power.
Please observe the safety regulations of elec-
trical engineering and industrial safety and lia-
bility associations!
Disregarding these safety regulations may re-
sult in death, serious personal injury or dam-
age to equipment.
Startup, mounting, modifications, and up-
grades should only be carried out by a skilled
electrical engineer!
WARNING: Risk of automatic machine re-
start!
For emergency stop applications, the ma-
chine must be prevented from restarting auto-
matically by a higher-level control system.
Protective covers must not be removed when
operating electrical switching devices.
WARNING: Danger due to faulty devices!
The devices may be damaged following an er-
ror and correct operation can no longer be en-
sured.
In the event of an error, replace the device im-
mediately.
Repairs to the device, especially if the hous-
ing must be opened, may only be carried out
by the manufacturer or authorized persons.
Otherwise the warranty is invalidated.
NOTE: Risk of damage to equipment due
to incorrect installation
For reliable operation, the safety relay must
be installed in housing protected from dust
and humidity (IP54).
Carry out wiring according to the application.
Refer to the “Application examples” section
for this.
NOTE: Risk of damage to equipment due
to noise emissions
When operating relay modules the operator
must meet the requirements for noise emis-
sion for electrical and electronic equipment
(EN 61000-6-4) on the contact side and, if re-
quired, take appropriate measures.
Only use power supply units with safe isola-
tion and SELV/PELV in accordance with EN
50178/VDE 0160 (SELV/PELV).

10 Function
Set the nominal input voltage to A1 and A2 - the power LED
lights up.
Now a voltage of 24 V DC is available at terminals S11 and
S21 that monitors itself for cross circuit.
Wire S12 and S22 according to the corresponding connec-
tion examples.
Bridge terminals S33 and S35 for automatic activation. The
safety relay starts automatically after the safety door closes.
The contacts 13/14, 23/24, 33/34, 57/58, 67/68 close and
the signal contact 41/42 opens. The LEDs K1, K2, K3(t) and
K4(t) light up.
If the input circuit is opened, relays K1 and K2 switch off
without delay and the LEDs extinguish. Relay K3t and K4t
switch off with delay.
To reactivate the safety relay, close the input circuits and
press the Reset button, if exists.
11 Configuration
To configure the safety relay, proceed as follows:
1Disconnect the safety relay from the supply voltage.
2Set the delay time (0,2s ... 300s).
3Restore the power supply.
4Close the emergency stop circuits.
5In the case of a manual start: press the reset button.
6 Automatic start circuit: wait for the configured delay
time until the enabling current paths are closed and the
Power LED lights up.
7 Manual start circuit: wait for the configured delay time
and press the reset button until the enabling current
paths are closed and the Power LED lights up.
11.1 Setting the delay time
The delay time of 0.2s to 300s is set in 24increments via
the rotary switch and the DIP switch in the upper housing
part.
1Set a time period using the DIP switches.
2Set the desired delay time with the rotary switch.
Figure 4 Configuring the time delay
11.2 Protection against manipulation
Once the time has been set, the rotary switch and the DIP
switch can be protected against manipulation by covering
with the label provided.
Figure 5 Applying the label
Once configuration is complete, close the four
enable current paths and the Power, K1/K2
and K3(t)/K4(t) LEDS are illuminated.
WARNING: Danger due to incorrect delay
time!
Check the set delay time following installation.
If the rotary switch is modified during opera-
tion, the safety relay switches to configuration
mode and the LEDs flash. The safety relay is
only ready for operation again once the supply
voltage has been switched off and on again
and configuration has been carried out.
