The GE Fanuc DS200TBQCG1AAA Module is a thermocouple and analog input termination board designed specifically for the Mark V Distributed Control System (DCS). Engineered for heavy-duty industrial gas and steam turbine management, this terminal board acts as the physical interface between field-level temperature sensors and the control cabinet electronics. It securely terminates thermocouple wiring, provides cold-junction compensation, and routes critical sensor signals accurately to the core processing modules while maintaining high signal integrity and noise immunity.
