FUNCTIONAL DESCRIPTION:

DS200TCQCG1AHD is an RST Analog Input/Output Expander Board manufactured and designed by General Electric as part of the Mark V LM Series used in the Line of Microprocessor aero-derivative turbine Control Systems. The RST Analog IO Expander board (TCQC) scales and conditions additional analog signals from the I/O core terminal boards. It provides LVDT and LVDR excitation. IONET termination for and is located on the TCQC board in the core, while the optional <21> termination is on the TCQC in . The TCQC board scales and conditions the mA input for the megawatt transducer signal, sending it to the STCA board through the 19PL connector. Pulse rate inputs are also processed on the TCQC board. High-pressure shaft speed signals and, in some cases, liquid fuel flow signals are scaled and transmitted to the TCQA board via the JE connector in the core. Additionally, the TCQC board communicates generator and line signals to the STCA board through the JE connector.

TCQC CONFIGURATION:

Hardware: The first 16 hardware jumpers on the TCQC board configure the servo output current range. Even-numbered jumpers control feedback scaling, while odd-numbered jumpers adjust the source output resistance. Jumpers 25 to 36 provide additional feedback scaling for servos one to four, allowing a maximum current range of ±240 mA. BJ17 configures the RS232 port for card testing, BJ21 enables the stall timer, and BJ22 activates the oscillator for factory tests. BJ23 and BJ24 are unused. BJ18 and BJ20 limit the P15 and N15 supply to proximity transducers. Jumpers JP38 and JP39 adjust the magnetic pickup gain for liquid fuel flow signals in certain applications.

TCQC GENERATOR AND LINE FEEDBACK:

Generator and line feedback signals are scaled and conditioned on the TCQC board before being sent to the STCA board through the 19PL connector. These signals originate from the TCTG board in the core, pass through the TCQA board, and reach the TCQC board via the JE connector. The STCA board utilizes these signals for the synch check function.
