IS200GGXIG1A Expander Load/Source Board
Description:
IS200GGXIG1A is a Expander Load/Source Board manufactured by GE. IS200GGXIG1A provides isolation and control between the high voltage power bridge and the Innovation SeriesTM board rack containing the IS200BICI Bridge Interface Controller Board (BICI) and the IS200BPII Bridge Power Interface Board (BPII). IS200GGXIG1A provides gating control, signal distribution, voltage isolation, and dc bus voltage indication. Also, it serves as a termination point for bridge attenuators and current sensors.

IS200GGXIG1A converts the RS422 signals into fiber-optic signals to gate the bridge IGCT (Integrated Gate Commutated Thyristor)switching devices. IS200GGXIG1A distributes the gate-control signals, terminates attenuators and current transformer current sensors, and provides analog feedback. The board can interface with up to 12 power devices. It sends scaled bridge voltage and current feedback signals to the BICl board.
