Functional Description

DS200TCQAG2B is an Analog I/O Board manufactured and designed by General Electric as part of the Mark V LM Series used in Speedtronic 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.

DS200TCQAG2B Configuration


  • 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.


  • Thermocouple, pulse rate, vibration, LVDT position, 4-20 mA input, and output I/O Configuration constants are entered in the I/O Configuration Editor.
  • It is found on the operator interface as explained below.

Pulse Rate Input Circuit

  • The circuitry that scales and controls the pulse rate inputs read from the TCQC board through the JE connector is located on the TCQA board. These signals come from the TTL (transistor to transistor logic) and magnetic pickup inputs, whose signals are sent to the QTBA and/or PTBA terminal boards.
  • The high-pressure shaft speed inputs are delivered to the "R1" core. Other signals may be used with the pulse rate input circuits on R2 and R3.

DS200TCQAG2B Thermocouple circuit

  • The terminal board is coupled to thermocouples. The thermocouple cold junction reference, which is used to compute the cold junction compensation, is provided by circuits that are likewise housed on the 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.
