Excessive speeds pose a danger to people and machinery. Using PSRmotion zero-speed and over-speed safety relays from Phoenix Contact, you can shut down quickly and safely in the event of an emergency.

Your advantages

  • Space savings of up to 75%, thanks to the compact design
  • Easy configuration via buttons on the product or using the PSRmotion software
  • Maximum compatibility, thanks to movement monitoring with all common sensor types
  • Maximum tamper protection, thanks to innovative protective mechanisms
  • PSRmotion zero-speed and over-speed safety relays are part of the COMPLETE line system

Compact zero-speed and over-speed safety relay

PSRmotion zero-speed and over-speed safety relay  

PSRmotion zero-speed and over-speed safety relay

With the PSR-MM30 combined zero-speed and over-speed safety relay, you can monitor up to three different operating modes in addition to zero-speed mode. The PSR-MM30 ensures high system availability, thanks to the reliable measuring procedure.

  • Overall width of 22.5 mm
  • Compatible with modern safety encoders up to SIL 3
  • Motion detection via encoder or proximity switch
  • Force-guided relay outputs, parameterizable signal outputs
  • Live monitoring with the PSRmotion software
  • Startup via USB connection
  • Compatible with PSRswitch safety switch, thanks to integrated safety door monitoring
  • Up to PL e and SIL 3

Live monitoring via PSRmotion software

PSRmotion software  

PSRmotion software for the compact zero-speed and over-speed safety relay

The PSR-MM30 zero-speed and over-speed safety relay can be started up, configured, and monitored conveniently using the PSRmotion software.

In live measuring mode, you can visualize the motion sequences of your machine.

You can download the Windows-based software free of charge. The software is then adapted via a USB interface.

Highly compact zero-speed monitoring without additional sensors

PSRmotion sensorless zero-speed safety relay  

The PSRmotion highly compact zero-speed safety relay does not require any additional sensors

With the narrow PSR-MM25 zero-speed safety relay, machine zero speed is monitored without the need for additional sensors, and an interlocking device is actuated, for example. Zero speed is detected by evaluating the voltage induced in a motor winding.

  • Overall width of 12.5 mm
  • Easy startup via configuration button
  • Can be used for machines with and without frequency converters
  • Force-guided relay outputs, two signal outputs
