Product Short Description
Product Overview
The IS200TSVOH1B is a high-performance, barrier-type servo valve termination board designed by General Electric (GE). It is a critical component of the Mark VI Speedtronic turbine control system, serving as the interface between the main control system and electro-hydraulic servo valves, as well as Linear Variable Differential Transformer (LVDT) position sensors. This board ensures precise, reliable, and safe control of industrial gas and steam turbines.
