IS200TSVOH1B Functional Description
The General Electric IS200TSVOH1B Servo Terminal Board is a highly specialized Servo Terminal Board designed for use within the Mark VI turbine control system. As a key component, the Mark VIe General Electric IS200TSVOH1B connects to two electro-hydraulic servo valves that control steam and fuel valves, integral to the turbine’s operation. This interaction is critical for the precise regulation of turbine performance, where the servo valves adjust the flow of steam and fuel based on real-time system demands.
Equipped with Linear Variable Differential Transformers (LVDTs), the IS200TSVOH1B Speedtronic Termination Board Servo Turbine Control accurately measures the position of the valves, ensuring smooth and responsive control. The LVDTs provide precise feedback, allowing the control system to make immediate adjustments, ensuring turbine efficiency and safety under varying operational conditions.
Connectivity plays a pivotal role in the functionality of the Servo Terminal Board IS200TSVOH1B. It features two cables connecting to the I/O processor (VSVO) via the J5 plug on the front of the board. Additionally, it interfaces with the VME rack’s J3/4 connectors, providing a robust communication link essential for real-time control and monitoring.
For advanced configurations, the IS200TSVOH1B General Electric PDF supports Simplex and Triple Modular Redundant (TMR) signaling through various connectors. JR1 is used for Simplex signals, while JR1, JS1, and JT1 facilitate TMR signals, ensuring high-reliability communication. The board also includes JD1 and JD2 plugs for external trip signals from the protection module, enhancing overall system safety.

Operation
The servo board has four channels: bi-directional servo current outputs, LVDT position feedback, LVDT excitation, and pulse rate flows inputs. The TSVO can excite and accept input from up to six LVDT valve position inputs. For each servo control loop, one, two, three, or four LVDTs are available. These signals come through TSVO and go directly to the VSVO board front at J5 if three inputs are used.
In Simplex applications, each servo output channel can drive one or two coil servos, while in TMR applications, each servo output channel can drive two or three coil servos. The two-coil TMR applications are for 200# oil gear systems with two control modules driving one coil each and no servo coil interface on the third control module.
With a maximum two-way cable resistance of 15 ohm, servo cable lengths of up to 300 meters (984 feet) are supported. Because servo coils come in a variety of shapes and sizes, a number of bidirectional current sources are jumper selectable.
