GE IS200TSVOH1BBB Servo Termination Board for Mark VI Turbine Control

The GE IS200TSVOH1BBB is a servo valve termination board (TSVO) designed for General Electric’s Mark VI Turbine Control Systems, used in gas, steam, and wind turbine control systems—an upgrade from the Mark V series with expanded wind turbine compatibility. It serves as a critical interface for three-coil servo actuators in Speedtronic applications, processing low-level signals: 0 to ±50 V DC analog, <24 V AC, and 4–20 mA current loops.

Physically, it features six D-shell connectors, two terminal strips, four transformers, and components like transistors, relays, and integrated circuits. Notched along long edges with three corner drill holes, it weighs ~2.00 pounds and includes six jumpers ,each with six settings. Part of the IS200 series, it has a conformal PCB coating and is identified via its product number coding. 

Features:
1.Servo Control Interface: Connects to three-coil servo actuators, handling diverse low-level signals for precise turbine actuator control.

2.Mark VI Compatibility: Integral to Mark VI systems, supporting gas, steam, and wind turbines, enhancing versatility over prior Mark V models.

3.Robust Hardware: Includes six D-shell connectors, terminal strips, transformers, and configurable jumpers (6 settings each) for flexible setup.

4.Durable Design: Conformal coating, notched edges, and drilled corners ensure resilience in industrial turbine environments.
