Description
 

The Macromatic PMD120 is a multi-detection phase monitor relay. This DIN-Rail mount relay has a single adjustable nominal voltage range of 102-138V. It monitors against 5 different types of phase errors and has an output of 10A DPDT. The PMD120 features different settings that can be adjusted for the best phase protection for the job, including an automatic and manual reset. The LED shows the current status and specifies a particular phase error. The PMD120 features a housing which is mountable on a 35mm DIN-Rail. Note: Image is an approximation. Actual part may differ.

Additional Product Information

The PMD120 features "True RMS voltage measurement". This has analog to digital sensing circuitry that gives more precise monitoring of phases and voltages. A useful feature in the PMD120 is that it can still monitor all the voltages while indicating the fault, even if a phase is lost. When the right voltage is introduced and it has the proper phase sequence, the relay becomes energized after the Restart Delay is finished. When an error is detected, the relay is de-energized after a delay, and will re-energize automatically once the error is fixed, unless the manual reset has been established.
