Description
The GE IS200ESELH3A Exciter Selector Board is a critical signal distribution module within the EX2100 excitation system. Mounted in the control rack, it receives six logic-level gate pulse signals from the EMIO master I/O board and routes them to six EGPA gate pulse amplifier boards located in the Power Conversion Cabinet. This board ensures precise gating control for exciter operation, with no jumpers or testpoints required for configuration.
