Safety relay module for sensor-free speed and speed range monitoring up to SIL 3, Cat. 4, PL e, 2-channel evaluation of the rotating field of AC and three-phase motors, plug-in screw terminal block, width: 12.5 mm
Excessive speeds pose a danger to people and machinery. The compact PSRmotion over-speed safety relays and zero-speed safety relays monitor and disconnect rotating parts safely in the event of an emergency. The switching devices are compatible with all common sensor types and can be configured and commissioned particularly quickly using buttons on the product or using software.More information
The safe PSR-MM35 over-speed safety relay reliably monitors speeds and thus protects against dangerous motion. You can monitor motion very economically and efficiently without any additional sensors.
With the PSR-MM30 combined over-speed and zero-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 with its reliable measuring procedure.
Our over-speed and zero-speed safety relays can be started up, parameterized, and monitored conveniently with 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.
The narrow PSR-MM25 zero-speed safety relay monitors machines for zero-speed situations without the need for additional sensors and actuates an interlocking device, for example. The zero-speed state is detected by evaluating the voltage induced in a motor winding.
