About the IS200EXHSG4AEC

The IS200EXHSG4AEC is an exciter relay driver board for an EX2100 Excitation System. The abbreviation used by GE for this board and it's family is EXHS. Information regarding the EX2100 migration pattern can be found in the GEZ-S2045 product life cycle documentation. 

The IS200EXHSG4AEC is a Static Exciter Terminal Board for use in high-speed applications.  The EXHS board is built as an identical board to the EXTB board with the exception of the replacement of a solid state relay driver on the EXHS board for the 41 DC contactors on the EXTB board.  If you are running high-speed application, please order an EXHS board, as an EXTB will not meet the needs of your system.

The IS200EXHSG4AEC is built with seven relays on its surface.  Each of these relays carries a reference designator that ends in M1, M2, or C.  The board has multiple connectors, including two conduction sensors, three ribbon connectors, and eight (female) plugs of various sizes.  The board has one heat sink located near the center of the board. It has integrated circuits and several transistors. Resistors and capacitors are of mixed materials.   It is worth noting that some component locations have been marked but hold no component; these are components that vary from board versions and are not needed for this version.
