GE DS200TCQAG1B RST Analog I/O Board

The DS200TCQAG1B (commonly referred to as the TCQA board) is the main analog I/O interface board in the RST core (R1, R2, R3) of the GE Mark V Speedtronic control system. This interface board functions as the "sensory nerve endings" of the control system, responsible for acquiring, conditioning, and scaling nearly all field analog signals-from turbine speed, vibration, and temperature to combustion chamber pressure and servo valve position feedback. The board processes these physical signals into digital signals readable by the control system processor, while outputting control commands in the form of current to actuators.
