This heavy-duty hardware component provides the direct physical termination interface for electro-hydraulic servo valves and their corresponding position feedback sensors, such as LVDTs or RVDTs. It bridges the raw field signals from the turbine deck to the internal VSVO servo control processor boards housed in the VME rack cage. Installing this Brand New, original GE terminal board eliminates signal loss across long field cable runs and secures precise fuel valve regulation to avoid unexpected thermal trips.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cp\u003eThe table below outlines the electrical interfaces, hardware configurations, and environmental boundaries
