7 Application examples using the modular safety relay
system
7.1 PSR-SDC4/2x1/B master module
Automatic operating mode
detection
The intelligent master safety relay automatically identifies the desired operating mode via
the sensor connections. This means that switches do not have to be set on the device.
The clearly arranged design of the modular safety relays helps you to quickly localize errors
in your safety circuits.
Your advantages:
– Fast installation
– Error-free startup
– Easy error localization

Safe cross-wiring with
PSR-TBUS
PSR-TBUS DIN rail connectors help establish a robust and safe connection between the
master module and extension modules. This renders the usual cross-wiring for the supply
voltage, the enable signal, and the confirmation current path redundant.
Fast system extension Up to ten safety relays can be easily connected to a PSR-TBUS DIN rail connector to create
a safety system with 42 contacts.
