GE IS200EAUDH1A Excitation Control High-Speed Contactor Driver Board

Product Description

The IS200EAUDH1A is a GE Speedtronic Mark VI series excitation high-speed contactor driver board, designed for the EX2100 generator excitation control system. It outputs drive signals to control excitation contactors, performs fast switching and protection action for the excitation loop. It communicates with the exciter main I/O board via the VME backplane, collects contactor status feedback, and executes trip logic when excitation faults occur. It is a dedicated core board for generator excitation cabinets in power plants.

FAQ

Q: Which system does IS200EAUDH1A belong to?
A: It is for GE Mark VI Speedtronic and EX2100 excitation control system, not Mark VIe.

Q: What is the difference between IS200EAUDH1A and IS200EAUXH1A?
A: IS200EAUDH1A is high-speed contactor driver board; IS200EAUXH1A is exciter auxiliary I/O interface board.

Q: Is this board discontinued?
A: Yes, Mark VI EX2100 series is end-of-life, only available as surplus, refurbished tested spares.

Q: Can it work independently?
A: No, it must cooperate with exciter main I/O board and excitation controller in the same rack.
