Description
🔹 Product Description
The GE IS200FOSAG1A is a Fiber Optic Interface Board, identified by the functional acronym FOSA, used within GE Mark VI/Mark VIe-era control and Innovation Series drive architectures. The board is installed on the Control Assembly Backplane (CABP) and provides fiber-optic interfacing between control electronics and associated power-device gate-driver circuitry. It is used in applications including low-voltage Innovation Series AC drives and certain 2300 V drive control cabinets. The board has a simple front-face design without LED indicators and can participate in a fiber-optic connection test with an associated IGBT gate-driver board. The related designation IS200FOSAG1AAA should be matched carefully with the exact hardware revision and system configuration before replacement.
