DS215TCQAG1BZZ01A is an Analog I/O Board manufactured and designed by General Electric as part of the Mark V LM Series used in turbine control systems. The Analog IO Board (TCQA) scales and conditions a large number of the analog signals that terminal boards mounted on the I/O cores R1, R2, and R3 read in. Included in this group of signals are the LVDT inputs, servo valve outputs, thermocouple inputs, 4-20 mA inputs and outputs, vibration inputs, relay driver outputs, pulse inputs, voltage inputs, and generator and line signals. On the STCA board, some of the signals are written via the 3PL connector. Through the JE connector, the TCQC board receives and transmits generator and line signals. The TCQA board scales and conditions input signals that are 420 mA, including the fuel flow pressure and compressor stall-detect signals.

 
TCQA CONNECTORS:

2PL - Distributes electricity to the, and cores from the TCPS board.

3PL - The Data Bus between the STCA, TCQA, and TCQE boards in the cores as well as between the STCA, TCQA, and TCQE boards in the core. For transmission to the COREBUS, conditionally conditioned signals are conveyed on 3PL.

JA - Carries the thermocouple inputs and cold junction correction for the corresponding R1, R2, and R3 cores from the TBQA board connection JAR/S/T.

JB - Carries the inputs and outputs for 4-20 mA to and from the JBR terminal board connection on the TBQC.

JD - Transports trip signals from the R1 core to the TCTG board in the P1 core; not utilized in R2 or R3.

TCQA CONFIGURATION:

HARDWARE: The mA output circuits are chosen using hardware jumpers J1 and J2. The mA outputs current range, either 20 mA maximum or 200 mA maximum, is configured using J5 and J6. For card tests, the RS232 port is connected to J7. An oscillator is activated by J8. For details on the hardware jumper settings for this board, consult Appendix A and the operator interface's hardware jumper panel.

SOFTWARE: The following describes how to enter I/O Configuration constants for the 4-20 mA inputs and outputs, vibrations, LVDT locations, pulse rates, and thermocouples in the I/O Configuration Editor on the operator interface.

PULSE RATE INPUT CIRCUIT:

The TCQA board houses the circuitry that scales and conditions the pulse rate inputs read from the TCQC board through the JE connector. These signals come from the magnetic pick-up inputs and TTL (transistor to transistor logic) inputs, whose signals are sent to the QTBA and/or PTBA terminal boards. The inputs for the high-pressure shaft speed go to the "R1" core. Additional signals may be used with the pulse rate input circuits on R2 and R3.

TCQA 4-20 mA INPUT CIRCUITS:

The circuitry for the 0-1 mA and 4-20 mA input signals is provided by the TCQA board. Through the JB connector, the signals are read from the TBQC terminal board. The voltage drop is measured by the TCQA board and written to the I/O Engine via the 3PL connector as the transducer current is reduced across a burden resistor. The current range of the input signals is chosen using hardware jumpers on the TBQC terminal board.

TCQA 4-20 mA OUTPUT CIRCUITS:

The circuitry for driving 4-20 mA outputs to the TBQC terminal board through the JB connector is provided by the TCQA board. Usually, these signals are utilized to power control equipment.

TCQA THERMOCOUPLE CIRCUIT:

The TBQA terminal board is coupled to thermocouples. The thermocouple cold junction reference, which is used by TCQA to compute the cold junction compensation, is provided by circuits that are likewise housed on the TBQA terminal board. The actual temperature read by the thermocouple is determined by the TCQA board using the thermocouple input and compensation setting. Via the 3PL connector, the I/O Engine reads the value. I/O configuration constants are used to select the types and curves of thermocouples.
