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 higher-level control systems in the process industry
  • Simple verification possible, as all safety characteristic data is available

 

PSRmini - highly compact, safe coupling relays

PSRmini is the newly developed safety relay range from Phoenix Contact. Thanks to its proprietary relay technology, the new coupling relays are extremely compact.

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

 

PSRclassic - classic safe coupling relays

In the PSRclassic series, you will find the conventional coupling relays with force-guided contacts for safe start-up and shut down.

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

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.

 

SIL – coupling relay for switching on safely

Switching on safely is becoming more and more important. Phoenix Contact is providing a coupling relay specifically to cater for this in the form of the PSR-ETP with the following properties:

  • Optionally switchable line/load monitoring
  • Special design for avoiding spurious trips
  • Notification of wire breakage over 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

The Termination Carrier module rack fits 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 high packing density
  • Robust, for high system availability
  • Flexible, for optimum adaptation
  • Fast thanks to error-free plug and play cabling
