1. Short description
PSR-TRISAFE-S is a freely configurable safety
module with 20 safe inputs and 4 safe outputs. It
also features four monitoring outputs, two clock
outputs, and two ground switching outputs.
The safety module evaluates different types of
safety equipment such as emergency stop buttons
or safety doors. The required safety functions are
freely configurable with the SAFECONF software.
The safety module can be used in safety circuits as
per EN 60204-1 and is suitable up to:
- Category 4 (EN 954-1)
- SIL 3 (IEC 61508)
- SILCL 3 (IEC 62061)
- PLe (ISO 13849-1)

2. Safety notes:
3. Function
The device operates with an operating voltage of 24 V DC. When the input voltage is applied at A1 and
A2 for the logic supply, and at 24 V and 0 V for the output supply, the device is ready to operate. The
SAFECONF software can now be used for configuration.
The four digital safe outputs are controlled following evaluation of the incoming signals in accordance with
the configuration created using the SAFECONF configuration software and loaded to the PSR-TRISAFE-S
safety module via the USB interface.
Two of the safe outputs can be used to switch the ground of a single-channel load (e.g., of a solenoid valve).
PSR-TRISAFE-S also has four non-safety-related digital monitoring outputs (M0 to M3) which can be
used to control a standard PLC or signaling units, for example.
The two asynchronous test pulses at T0 and T1 enable safe cross-circuit detection at the controller inputs.
All connection terminal blocks can be plugged in. The individual terminal block bases are mechanically
keyed to prevent confusion or connecting them the wrong way round. PSR-TRISAFE comes with a choice
of screw connections or spring-cage connections.
• 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.
• The device may only be started up,
assembled, modified, or retrofitted by an
authorized electrician.
• The device must be operated in a closed
control cabinet.
• Before starting work, disconnect the device
from the power supply!
• For emergency stop applications, the
machine must be prevented from restarting
automatically by a higher-level control
system.
• During operation, parts of electrical
switching devices carry hazardous voltages.
• Danger! During operation, the protective
covers must not be removed from the
electric switchgear!
• In the event of an error, replace the device
immediately.
• Repairs to the device, especially those
involving opening the housing, may only be
carried out by the manufacturer or by a
person authorized by the manufacturer.
Otherwise the warranty is invalidated.
• Please retain the instructions.
