Description
The GE General Electric IS200WSVOH1A, identified as IS200WSVOH1ABA in the supplied listing, is a Servo Driver Board Assembly used in GE Mark VI/Mark VIe turbine control applications. The WSVO assembly is associated with servo control functions and includes servo current-regulator circuitry, configurable gain settings, servo protection relays, and excitation output driver circuitry. Technical references identify the board as working with the PSVO I/O pack and TSVC/SSVP-related servo interfaces, depending on the specific Mark VIe configuration. The IS200WSVOH1A is also used as the internal functional board within the larger IS210WSVOH1A Servo Driver Assembly.
