What Is the GE IS200EISBH1AAA Exciter ISBus Board? Why It Matters?

Apr 21, 2026
What Is the GE IS200EISBH1AAA Exciter ISBus Board?

IS200EISBH1AAAis an Exciter ISBus Board manufactured and designed by General Electric as part of the EX2100 Series used in GE Excialion Contol Systems. TheS200EISB Exciter Bus Board (EISB) s a specdial communication board for the M1, M2, and C controllrs. It receives and transmits fiber-optic fedback signals andtansmits them over the contol backplane to the DSPx controller and also communicaes between the Dsx and the too and keypad ports using RS 232C through theackbone conector In addtion, for redundant exciters, EISB contains SBus interface electronics. ISBus is a GE propretary communications nterface, used here totransfer data among the M1, M2 and Ccontrollers of the exciter ESB is a single sot 3U-high module thatis located in the contol rack under the DSPx From fber-opticonnectors on the font panel it accepts curen and yolage sional from the generalor field (and from the Excter f requred) using EDCF boads and receves andtransmits signals to the Ground Detection module.
