The GE Energy IS200TSVCH1A is a Servo Input/Output Terminal Board designed for the Mark VIe Turbine Control System series. It provides interface connections for two electro-hydraulic servo valves used to actuate steam and fuel valves in turbine drive assemblies. The board accepts inputs from up to eight Linear Variable Differential Transformers (LVDTs) for valve position measurement and integrates two pulse rate signals for gas turbine fuel flow monitoring. Designed with conformal coating on its PCB assembly, the unit supports simplex, dual, and TMR control configurations and communicates with the WSVO servo driver and PSVO I/O pack.
