GE DS200TCCAG1B Mark V Common Analog I/O Board

DS200TCCAG1B handles 4–20 mA inputs and outputs, RTD and thermocouple inputs, and shaft voltage/current monitoring. The field circuits connect through the appropriate CTBA, TBQA or TBCA termination board.

DS200TCCAG1B uses CTBA for current-loop and shaft-monitoring paths, TBCA for RTD inputs, and TBQA for thermocouple and cold-junction information. Each path has a distinct connector assignment.

DS200TCCAG1B uses the 3PL data-bus connection to transfer scaled and conditioned signals to the associated STCA and I/O engine. The 2PL connection supplies power from TCPS.

DS200TCCAG1B carries the 4–20 mA output signals to CTBA through JAA. JBB is the separate connection used for current inputs and shaft-voltage/current signals from CTBA.

DS200TCCAG1B reads RTD signals from TBCA through JCC and JDD. Its circuitry provides RTD excitation, measures the resulting signal and applies the configured temperature scaling.

DS200TCCAG1B uses thermocouple inputs and cold-junction information from TBQA to calculate compensated temperature values. The installed I/O configuration selects the thermocouple type and associated curve.
