Description
 

The Macromatic VMP012D is a voltage monitor relay, for equipment that could be susceptible to damage in an under or over voltage situation. This 8 Pin plug-in relay has a nominal voltage of 12V DC. It checks for over or under voltage errors and has an output of 10A DPDT. The VMP012D has an adjustable pick-up voltage, a fixed drop-out time delay and a fixed drop-out voltage. The VMP012D features an LED that is red when the unit is energized or green when it is not. It uses an 8 Pin 70169-D octal socket. Note: Image is an approximation. Actual part may differ.

Macromatic VMP Series Relay Installation Instructions

VMP012D 12V Over/Undervoltage Monitor Relay

Additional Product Information

When the voltage stays above the preset pick-up voltage (9-15V DC) for a longer period than the pick-up time delay, then the unit is energized. If the voltage goes below the drop-out for greater duration than the drop-out time delay, then it de-energizes. The drop-out time delay is fixed at 0.5 seconds. It uses true RMS voltage measurement for more precise monitoring. Whether the VMP012D operates for undervoltage or overvoltage protection is subject to the kind of output contacts being used.

Overvoltage
Overvoltage protection makes use of a normally closed contact. The voltage needs to stay below the max voltage for the load to be energized while the relay itself remains de-energized. If the voltage goes above this level, the reverse happens, until voltage goes back down.

Undervoltage
Undervoltage monitoring requires a normally open contact. The load stays on and the relay is energized if the voltage stays above the minimum voltage. Voltage going below the minimum de-energizes both the load and the relay.
