Zero-speed and over-speed safety relays monitor rotating parts and shut down safely in the event of an emergency.
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.
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.
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.
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.
