The Macromatic VWKP120A is a voltage monitor relay. This 8 Pin plug-in relay has a nominal voltage of 120V AC and an output of 10A DPDT. This voltage band relay is used for equipment that has to work within a certain voltage range. The VWKP120A features adjustable over and under voltage presets, as well as an adjustable drop out time delay ranging from 0.1-10 sec. The VWKP120A has an LED that is red to indicate 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.

Additional Product Information

When the voltage stays between the preset over and under voltage settings, the unit stays energized. If the voltage goes over or under the preset range for a greater duration than the drop-out time delay, it de-energizes. Once the voltage goes back within the safety range for a longer duration than the 0.5 sec pick up delay, the relay is energized again.
