Motor Insulation Tester

This electronics module is a compact, solid-state 12-pin plug-in instrument that can be installed into new or existing control panels. When a motor start signal is applied to pin 3 of the electric motor winding insulation monitor, a yellow LED light will show that 500 V of direct current are being applied to the motor winding. If the winding is good, the unit completes the megging operation, and the motor start signal then is connected from pin 3 to pin 4. If the winding is bad, the low-meg red LED comes on and the motor start signal will not be available to engage the motor starter.
