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.

❓ Q&A
Q: What is the GE IS200WSVOH1A?
A: It is a GE Mark VI/Mark VIe Servo Driver Board Assembly used for servo-control functions in compatible turbine control systems.
Q: What does WSVO stand for?
A: WSVO is the functional acronym associated with this GE servo driver assembly.
Q: How many servo current regulators are included?
A: The documented assembly includes two servo current regulators.
Q: How many configurable gains are available?
A: The servo driver circuitry provides five configurable gain settings.
Q: What power supply does the board use?
A: The servo driver assembly accepts a P28/+28 V input and provides approximately +15 V and -15 V internal supply rails.
Q: Which I/O pack is associated with the WSVO assembly?
A: The IS200WSVOH1A is documented with the PSVO I/O pack.
Q: Is IS200WSVOH1A the same as IS210WSVOH1A?
A: They are closely related but are not the same complete part. The IS210WSVOH1A is a larger Servo Driver Assembly that contains the IS200WSVOH1A functional board.
Q: What should I verify before replacement?
A: Verify the complete board number, revision, associated terminal board, I/O pack, field wiring, and the original Mark VIe application configuration before installation.
