The IS200EISBH1AAA is an Exciter ISBus Board manufactured and by General Electric as part of the EX2100 Series used in GE Excitation Control Systems. The IS200EISB Exciter ISBus Board (EISB) is a special communication board for the M1, M2, and C controllers. It receives and transmits fiber-optic feedback signals and transmits them over the control backplane to the DSPX controller and also communicates between the DSPX and the tool and keypad ports using RS-232C through the backbone connector.

 
In addition, for redundant exciters, EISB contains ISBus interface electronics. ISBus is a GE proprietary communications interface, used here to transfer data among the M1, M2, and C controllers of the exciter. EISB is a single-slot, 3U-high module that is located in the control rack under the DSPX. From fiber-optic connectors on the front panel, it accepts current and voltage signals from the generator field (and from the Exciter if required) using EDCF boards, and receives and transmits signals to the Ground Detection module.
