Product Description
IS200TSVOH1B GE Mark VI
Product Overview
The IS200TSVOH1B is a Servo I/O Terminal Board designed to act as the signal interface and drive node between the controller and field electro-hydraulic servo valves and LVDT displacement sensors. It converts control system commands into precise current drive signals that servo valves can execute, while simultaneously acquiring valve position feedback to achieve closed-loop control.
Belonging to the IS200 series, this board serves as the critical end-point execution component of the servo control loop in the Mark VI/VIe architecture. It is widely used for the drive and position control of key actuators — such as fuel valves, steam control valves, and bypass valves — in gas turbines, steam turbines, and large compressor units.
The board features barrier terminal blocks and DC-37 cable connectors and is designed for panel mounting, connecting to the VSVO servo control board via cable. In the Mark VIe architecture, it is typically used in conjunction with the IS220PSVO servo I/O package; in the Mark VI architecture, it interfaces with the IS200VSVO servo control board.

Application Case Example
In a gas turbine control system retrofit project, the wiring of the original system's servo valves had deteriorated, causing occasional fluctuations in the LVDT feedback. After replacing the terminal block with an IS200TSVOH1B model, the two servo channels of the fuel valve were connected separately, and multiple LVDT feedback inputs were configured for each channel.
The VSVO board executes the servo control algorithm, while the TSVO handles field signal conversion and redundancy distribution. After commissioning, the stability of the valve position feedback improved. During shutdowns for maintenance, LVDT excitation and feedback signals can be quickly measured via the terminal block, reducing troubleshooting time.
Frequently Asked Questions
How many servo valves can it connect to?
The IS200TSVOH1B typically provides 2 servo I/O channels. If more channels are required, additional terminal blocks must be added or other configurations used, depending on the system architecture.
What is the maximum number of LVDTs that can be connected?
Up to 6 LVDT/LVDR valve position sensors can be connected. Depending on reliability requirements, 1 to 4 sensors can be selected per servo loop.
Does it support TMR triple redundancy?
Yes. The TSVO can distribute signals to redundant channels via different connectors; however, the specific wiring method must follow the GE manual and project configuration.
What is the warranty period for this module?
Typically, the warranty period for original products is 12 months.
