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

  • Flexible use, with three selectable operating states
  • Fast startup, thanks to configuration directly on the device or via free 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 relay  

PSRmotion zero-speed and over-speed safety relay

With the narrow PSR-MM30 zero-speed and over-speed safety relay, you can monitor the speed of moving machine parts and shut these down safely in the event of danger. Along with zero-speed monitoring, you can also monitor up to three different operating modes. The PSR-MM30 ensures high system availability, thanks to the reliable measuring procedure.

Thanks to the additional integrated safety door monitoring system, the zero-speed and over-speed safety relay is compatible with the PSRswitch safety switches.

 

Main features:

  • Slim design of 22.5 mm
  • Compatible with modern safety encoders up to SIL 3
  • Up to SIL 3 and PL e
  • Motion detection via encoder or proximity switch
  • Startup via USB connection
  • Force-guided relay outputs
  • Configurable signal outputs
  • Live monitoring with the PSRmotion software

Live monitoring via 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

Sensor-free zero-speed safety relay  

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

With the narrow PSRmotion 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.

Thanks to application-specific setting options, PSRmotion is extremely flexible to use, both for machines with and without frequency converter.

The highly compact zero-speed safety relay saves up to 70% space. This makes it ideal for retrofitting.
