Description
 

The Macromatic VMP024D is a voltage monitor relay. This 8 Pin plug-in relay has a nominal voltage of 24V DC. It checks for over or under voltage errors and has an output of 10A DPDT. The VMP024D has an adjustable pick-up voltage, a fixed drop-out time delay and a fixed drop-out voltage. The VMP024D has an LED indicator that glows red when the unit is energized or green when it is not. It uses an 8 Pin 70169-D octal socket and true RMS voltage measurement for more precise monitoring. Note: Image is an approximation. Actual part may differ.

Macromatic VMP Series Relay Installation Instructions

VMP024D Over/Under DC Voltage Monitor Relay
Additional Product Information

When the voltage stays above the preset pick-up voltage (18-30V 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. Whether the VMP024D operates for undervoltage or overvoltage protection is based on the kind of output contacts being used.

Overvoltage
Overvoltage protection utilizes a normally closed contact. The voltage has 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.
