The DS200EXDEG1A is a Mark V series DE-Excitation Control Board. 2 34-pin connectors, 2 10-pin connectors, and 5 indicator LEDs are included on the GE Excitation Control Board DS200EXDEG1A. There are also 8 capacitors, test points, and terminal connectors on the board. The capacitors store high-voltage current during normal processing, and when a signal is received, a circuit on the board releases the high voltage. The same circuits start the process of storing high-voltage current all over again.
