The Macromatic PMP120 is a multi-detection phase monitor relay. This 8 Pin plug-in relay has an adjustable nominal voltage of 102-138V. It monitors against 5 different types of phase errors and has an output of 10A SPDT. The LED indicator changes color to show the status or specify a particular phase error. It is green when everything is normal or changes to red when it detects an error. The diagram on top of the unit shows how the LED will display an error. The PMP120 uses an 8 Pin 70169-D octal socket.

The PMP120 features "True RMS voltage measurement". Analog to digital sensing circuitry in True RMS voltage measurement allows the relay to be more accurate in monitoring phases and voltages. One unique feature for this series is that even if a phase is lost, it can still monitor all the voltages as well as indicate the fault. When the voltage and phase sequence is right, the relay becomes energized after the Restart Time Delay. When an error is detected, the relay is de-energized, and will re-energize once the error is fixed unless the manual reset is set up.
