GE IS200EISBH1AAA IN-SYNCH-BUS card
Description：
IS200EISBH1AAA is part of GE EX2100 products, iIS200EISBH1A is a special communication interface board for the M1, M2, and C control modules. ISBus is a proprietary, high-speed communication bus used in many GE systems. IS200EISBH1A is used to provide communication among the 3 DSPSs in M1, M2, and C. IS200EISBH1A receives and transmits fiber-optic feedback signals through the backplane connector. It 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. EISB is a single-slot, 3U high module that is located in the control rack under the DSPX. From six 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 (EGDM).
