The GE IS200RCSAG1ABB is an RC Snubber Assembly, a modified version of the IS200RCSAG1 parent board with three revisions. It is part of GE Industrial Systems' EX2100 Excitation Control System, functioning as an RC Snubber Board.

Purpose: Provides snubber circuits for 1800 or 1000 Innovation Series nonregenerative SCR/diode modules and offers noise isolation for gate drive circuits.

Hardware: Features two sets of SCR and diode connections (distinguishing 1800/1000 frame units), two snubber circuits each with unique pulse width, frequency, and peak voltage based on resistance/capacitance measurement. No movable jumpers, but includes four factory-drilled installation holes.
