The GE IS200VSVOH1BDC is a Servo Control Board used in GE Mark VI Speedtronic turbine control systems. It is designed to manage electro-hydraulic servo valves that regulate critical turbine functions such as fuel flow, steam control, and inlet guide vane positioning.
This module executes closed-loop control algorithms, processes actuator feedback (LVDT/RVDT), and handles pulse-rate speed inputs to ensure precise mechanical positioning and stable turbine operation in high-demand power generation environments.
