The Macromatic PMPU is a three phase monitor relay. This 8 Pin plug-in relay has a nominal voltage of 190-500V. Voltage can be set between 190-250 for low voltage applications or 380-500 for high voltages. High or low voltage range is selected by the relay automatically. It monitors against 5 different types of phase errors and has an output of 10A SPDT. The LED is green when everything is normal or red to specify a particular phase error. The diagram on top of the relay depicts how the LED will indicate the current status. The PMPU uses an 8 Pin 70169-D octal socket.

The PMPU makes use of "True RMS voltage measurement". This features analog to digital sensing circuitry that gives more precise monitoring of phases and voltages. A special feature in the PMPU is that it can still monitor all the voltages while indicating the fault, even if a phase is lost. A socket that is rated for 600V should always be used if the system voltage is above 300V. When the voltage and phase sequence is right, the relay becomes energized. When an error is detected, the relay is de-energized, and will re-energize once the error is fixed, unless the manual reset has been established. To set up the manual reset, a normally closed switch needs to be connected to pins 6 and 7.
