DS200TBQBG1ACB | General Electric | Termination Board

Description

DS200TBQBG1ACB is a termination board from General Electric, designed for industrial control applications as part of the Mark V series, primarily used in gas turbine control systems. This board serves as a critical interface for signal and power distribution within control system cores, working in conjunction with related I/O and control boards such as TCQA, TCQE, STCA, and TCTG. It supports multiple signal types and connections: the 2PL channel distributes power from the TCPS board to system cores, while the 3PL data bus links core boards to transmit conditioned signals to the COREBUS. The board handles diverse input and output signals, including thermocouple inputs and cold junction compensation via connector JA, 4-20 mA analog I/O signals via connector JB, and trip signals sent to the TCTG board via connector JD. Additionally, it manages pulse signals, generator and line signals, relay driver outputs, and servo valve driver outputs via connector JE, plus LVDT/LVDR position inputs, +/-10 V DC inputs, and vibration inputs through dedicated connectors. Its core function is to support the scaling and conditioning of analog signals read from terminal boards installed in I/O cores R1, R2, and R3, ensuring reliable signal transmission and processing for precise gas turbine control.
