The GE DS200TCCAG1AJB Common Analog I/O Board is an industrial control module used in GE Speedtronic Mark V gas turbine control systems. It is part of the TCCA (Common Analog I/O Board) family, responsible for analog signal conditioning, scaling, and routing within the turbine control architecture.

The DS200TCCAG1AJB board functions as a central analog interface module inside the turbine control “core” (typically the R5 core). It collects analog signals from multiple terminal boards and converts them into conditioned signals for the control system’s processing unit.

It acts as a signal conditioning and interface hub, ensuring that sensor data is accurate, stable, and suitable for digital control logic processing.
