🔹 Product Description

The GE General Electric IS200FOSAG1A, also identified as IS200FOSAG1AAA, is a Fiber Optic I/O Board from the GE Mark VI control platform. The board is identified by the functional acronym FOSA and is mounted on the Control Assembly Backplane (CABP). It provides a fiber-optic interface within compatible GE drive and turbine-control architectures and can be used in Innovation Series drive applications. The board is associated with fiber-optic communication to an IGBT gate-driver board, with system-level fiber testing used to verify the connection. Its exact application and slot position should be matched to the existing control cabinet configuration before replacement.
