Product Description
IS200VSVOH1B
Product Overview
IS200VSVOH1B is a VME servo control board in GE's Mark VI series, specifically designed for turbine control systems. This model employs a highly integrated VME bus architecture, combining servo drive, LVDT position feedback, pulse flow input, and safety protection functions onto a single single-slot board.
It supports both simplex system configurations and operation within a Triple Modular Redundant (TMR) architecture, capable of meeting diverse requirements ranging from general industrial control to mission-critical turbine protection.
As one of the core control components of the Mark VI system, this board is specifically responsible for driving and controlling the fuel and steam valves of gas and steam turbines. It achieves closed-loop regulation of valve positions through precision electro-hydraulic servo valves and is hailed as the "valve brain" of the turbine unit.
With its industrial-grade rugged design and wide operating temperature range of -40°C to +85°C, the board is capable of long-term, stable operation in harsh environments such as power plants and petrochemical facilities, where high temperatures, strong electromagnetic interference, and high vibration are common.
Key Features

Case Study
At a heavy-duty gas turbine power plant, delayed fuel valve response had previously caused load oscillations. Traditional servo boards were prone to drift in high-temperature, high-vibration environments, resulting in a 12% drop in operational efficiency and annual economic losses exceeding 100 million yuan.
After introducing the IS200VSVOH1B as the servo hub for the Mark VI system, the board used high-precision position feedback algorithms to calibrate valve positions in real time, reducing valve oscillation by up to 95% and ensuring stable valve operation.
This improvement not only reduced unit startup time by 20% but also effectively eliminated the risk of cascading failures caused by valve oscillation, establishing the power plant as a reliable backbone node for the regional power grid.

Frequently Asked Questions
Can the IS200VSVOH1B directly replace the older IS200VSVOH1A or earlier H1 versions?
Yes. The IS200VSVOH1B is the official successor model released by GE and is backward compatible in terms of hardware pin definitions, VME interfaces, and software drivers. When directly replacing the older H1A with the H1B, there is no need to change external cables or rack configurations. However, it is recommended that after the replacement, you use ToolboxST to re-download the I/O configuration file for that slot and perform an automatic LVDT calibration to ensure optimal performance.
Does the IS200VSVOH1B support hot-swapping? What precautions should be taken during installation and removal?
Hot-swapping is not supported. You must completely power down the VME processor rack before inserting or removing the board. Operating the system while it is powered on may damage the board and the backplane.
How long will it take to receive my order after purchasing the IS200VSVOH1B?
