Whether in the process industry or machine building, reliable signal coupling must be ensured in the event of an emergency. Phoenix Contact offers coupling relays with force-guided contacts for this.

Your advantages

  • Maximum safety with force-guided contacts according to EN 50205
  • Safe diagnostics and easy proof test according to IEC 61508
  • High level of compatibility: tailored to control systems in the process industry
  • Simple verification possible, as all safety characteristic data is available

PSRmini – highly compact safe coupling relays

PSRmini highly compact safe coupling relays  

Space savings of up to 70% with PSRmini

PSRmini is the newly developed range of safety relays from Phoenix Contact. Thanks to the relay technology developed in-house, the new coupling relays are extremely space-saving. 

No wider than 6 or 12 mm, the new coupling relays with force-guided contacts offer a huge space-saving potential of up to 70% with full performance.

PSRclassic – conventional safe coupling relays

PSRclassic conventional safe coupling relays  

Conventional coupling relays for safe startup and shutdown

In the PSRclassic series, you will find the conventional coupling relays with force-guided contacts for safe startup and shutdown.

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

Safety through force-guided contacts

Force-guided contacts  

Force-guided contacts

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, failure to open can be reliably detected. This is the most reliable way to ensure maximum safety for both person and machine.

It goes without saying that the products in the PSRmini and PSRclassic series are equipped with force-guided contacts in order to provide maximum safety.

SIL – coupling relay for safe startup

Safe startup up to SIL 3  

Coupling relay for safe startup up to SIL 3

Switching on safely is becoming more and more important. With the PSR-ETP, Phoenix Contact is providing a coupling relay specially developed for this requirement with the following properties:

  • Optionally switchable line/load monitoring
  • Special design for avoiding spurious trips
  • Notification of an open circuit via the existing connection line from DO to A1: reading back the data separately becomes superfluous
  • All available characteristics and documents for easy configuration and loop calculation

Quick and reliable wiring with the Termination Carrier

Termination Carrier with PSRmini coupling relay  

Termination Carriers and PSRmini: unique packing density in the control cabinet

The Termination Carrier module carriers fit the PSRmini and PSRclassic. Use them to reduce the amount of wiring and speed up your installation. 

Thanks to a universal concept and specific system technology, with the Termination Carriers you avoid wiring errors, i.e., a cause of expensive and time-consuming troubleshooting.

Your advantages:

  • Compact, for a high packing density
  • Robust, for high system availability
  • Flexible, for optimum adaptation
  • Fast, thanks to error-free Plug and Play cabling

We'll be happy to adapt the Termination Carriers to suit your specific requirements.
