Products Overview
GE IS200EAUDH1A excitation control high-speed contactor driver board is a sub-board that is installed as an accessory on the excitation control auxiliary interface board. This board provides pick-up and drop-out control capability for the two contactor drive circuits on the EAUX board.
The IS200EAUDH1A board must be installed in a clean area, and its installation location must not be exposed to the risk of electric shock or arc flash from the excitation equipment.

Products Function
- Low-voltage coil drive: GE IS200EAUDH1A is optimized for driving low-voltage contactor coils rated at 30–32 V DC.
- High-voltage starting pulse: GE IS200EAUDH1A supports applying full voltage at the moment of startup (for 150 ms), allowing the contactor to pull in quickly.
- Energy management and freewheeling protection: GE IS200EAUDH1A is equipped with a low-impedance flyback circuit, providing a freewheeling path for the coil current during the PWM turn-off phase.
Products Application
The IS200EAUDH1A board is mainly used in the following industrial field scenarios and system configurations:
- Directly controls the field contactors used to connect and disconnect the generator rotor excitation circuit
- Enables smooth application of excitation current during the motor start-up sequence
- Supports rapid de-excitation during emergency shutdown procedures
- Controls excitation contactors in the excitation circuits of main generators and propulsion motors
- Deployed in Static Var Compensator (SVC) systems and synchronous condenser installations
