Excessive speeds pose a danger for 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 compact design
  • Easy configuration via buttons on the product or via the PSRmotion software
  • Maximum compatibility, thanks to movement monitoring with all common sensor types
  • Maximum protection against manipulation, thanks to innovative protective mechanism

Compact zero-speed and over-speed safety relay

PSRmotion zero-speed and over-speed safety relays  

PSRmotion zero-speed and over-speed safety relays

With the combined PSR-MM30 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 22.5 mm
  • Compatible with modern safety encoders up to SIL 3
  • Motion detection via encoder or proximity switch
  • Force-guided relay outputs, configurable signal outputs
  • Live monitoring with the PSRmotion software
  • Startup via USB connection
  • Compatible with PSRswitch safety switches, 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 commissioned, configured and monitored conveniently with the PSRmotion software.

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

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

Highly compact downtime monitoring without additional sensors

PSRmotion sensor-free zero-speed safety relay  

Highly compact PSRmotion zero-speed safety relays do not need any additional sensors

With the narrow PSR-MM25 zero-speed safety relays, machine downtime is monitored without the need for additional sensors, and an interlocking device, for example, is actuated. To detect downtime, a voltage induced in a motor winding is evaluated.

  • Overall width 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
