The modular PSR safety relay system
with PSR-TBUS connection
Our PSR safety relay system reduces the space
requirement in the control cabinet, simplifies
wiring and minimizes storage costs. The
multifunctional PSR-SDC4 master relay is able
to monitor signals from different types of safety
sensors and switches. The PSR-SDC4, that can
also be used as a standalone safety relay, is
simple to setup and requires no programming
or setting of dip switches. Safety relays can be
easily connected to the PSR-SDC4 via
PSR-TBUS connectors for input or contact
extension. The PSR-TBUS forms an integral
backbone for the control and feedback signals
to and from the extension units and significantly
reduces the wiring typically associated with
safety relays.
The safety-related wiring between the individual PSR modules is
enabled automatically via the PSR-TBUS DIN rail connector. Besides
the supply voltage, an enable signal and the feedback path of the
extension modules are led over the connector. The terminal plug closes
the feedback circuit in the system.
