The DS200TCQAG1B is an RST analog I/O board manufactured by General Electric and is part of the Mark V series used in gas turbine control systems. Many of the analog signals read by the end boards installed on the I/O cores R1, R2, and R3 are scaled and adjusted by the Analog IO Board (TCQA). LVDT inputs, servo valve outputs, thermocouple inputs, 420 mA inputs and outputs, vibration inputs, relay driver outputs, pulse inputs, voltage inputs, and generator and line signals are just a few of the signals included in this list. Through the 3PL connector, some signals are written to the STCA board. JE connectors are used to send and receive generator and line signals via the TCQC board. The TCQA board adjusts 420 mA input signals, such as compressor stall detection signals and fuel flow pressure signals.

The TCQA connectors are as follows

Power from the TCPS board is allocated to the kernel using 2PL.

The 3PL-data bus is the connection between the STCA, TCQA, and TCQE boards in the kernel. For transmission to COREBUS, conditional signals are transmitted on 3PL.

The thermocouple input and cold end compensation of the core are transmitted by JA from the TBQA board connector JAR/S/T, respectively.

The 4-20 mA input and output are connected by the JBR terminal board transmitted by the JB to the TBQC.

JD - is not used for OR, but sends trip signals from the kernel to the TCTG board in the kernel.

JE - Transmits pulse signals, generator and line signals, relay driver outputs, servo valve driver outputs, etc. to or from the TCQC board. Carries the input of the power monitor.

The TBQC terminal board connector JFR sends LVDT/LVDR position input to the JF.

The JG carries the +/ -10 V DC input and the vibration input from the TBQB terminal board connected to the JGR.

TCQA hardware and software configuration

Hardware: Select the mA output circuit using hardware jumpers J1 and J2. mA Output current range (maximum 20 mA) or maximum 200 mA, configured using J5 and J6. For card testing, the RS232 port is used in J7. J8 Turn on the oscillator. For more information about the hardware jumper Settings for this board, see Appendix A and the Hardware Jumper panel of the operating interface.

Software: Thermocouple, pulse rate, vibration, LVDT position, and 420 mA input and output I/O configuration constants are entered in the I/O configuration editor on the operating interface, as described below.

Pulse rate input circuit

The circuit used to adjust and adjust the pulse rate input to be read from the TCQC board via the JE connector is located on the TCQA board. These signals are fed from TTL (transistor to transistor logic) and magnetic pickup inputs into the QTBA and/or PTBA terminal boards. The high pressure shaft speed input is sent to the "R1" core. There are other signals that can be used with the pulse rate input circuitry on R2 and R3.

TCQA 4-20 mA input circuit

The circuits for the 420 mA and 01 mA input signals are provided by the TCQA board. The signal is read from the TBQC terminal board via the JB connector. The voltage drop at both ends of the load resistance is caused by the current drop of the sensor, measured by the TCQA board and written to the I/O engine via the 3PL connector. The current range of the input signal is selected using the hardware jumper on the TBQC terminal board.

TCQA 4-20 mA output circuit

The circuit to drive the 420 mA output to the TBQC terminal board via the JB connector is provided by the TCQA board. Typically, these signals are used to power control devices.
