PSRmini is the newly developed safety relay range from Phoenix Contact. Thanks to its proprietary relay technology, this series is extremely compact.

No wider than 6 or 12 mm, the new safety relay with force-guided contacts offers enormous space-spacing potential of up to 70% at full capacity.

The fine-grained architecture makes a modular design of safety concepts possible: the 6 mm version comes with one to two approval paths, the 12 mm version with two to three.

In the extensive PSRclassic product range, you can find the conventional safety relay with force-guided contacts to monitor your safety functions, such as emergency stop, safety gates, light grid, and two-hand control.

The conventional safety relays are characterized by a wide range of features and variations. With a housing width starting from 17.5 mm, they correspond with the market-standard housing dimensions.

With the PSRmodular modular safety relay system, you can assemble your safety system as required. Modular safety relays can be extended easily and flexibly based on the modular principle.

The TBUS connector connects the master safety relay to up to ten extension modules directly on the DIN rail. The usual cross-wiring and configuration is not necessary. 

The N/O and N/C contacts of an elementary relay are connected to one another mechanically through forced guidance. This prevents N/O and N/C contacts from closing at the same time. In conjunction with a suitable circuit, an N/O failure is reliably detected. This is the most reliable way of ensuring maximum safety of both man and machine.

Self-evidently, the PSRmini and PSRclassic product series are equipped with force-guided contacts to provide you with the highest level of safety.
