The Macromatic VWKP048D is a voltage monitor relay. This 8 Pin plug-in relay has a nominal voltage of 48V DC and an output of 10A DPDT. This voltage band relay works with equipment that must operate within a certain voltage range. The VWKP048D has adjustable over and under voltage presets, and an adjustable drop out time delay ranging from 0.1-10 sec. The VWKP048D 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.

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