Product Description
The DS200TCQAG1A is an Analog I/O Board manufactured by General Electric for the Mark V turbine control system. It scales and conditions analog signals received from terminal boards in the R1, R2, and R3 I/O cores. The board handles multiple signal types, including thermocouple inputs, 4-20 mA signals, LVDT/LVDR position feedback, vibration inputs, servo valve outputs, and generator signals.
Functional Description
The DS200TCQAG1A processes analog signals before transferring the conditioned signals to the COREBUS through the 3PL connector. It receives signals from terminal boards and provides the required signal conditioning for the Mark V control system.
Furthermore, the board handles 4-20 mA input signals associated with measurements such as fuel flow, pressure, and compressor stall detection. It also interfaces with servo valve driver outputs, relay driver outputs, pulse signals, and generator and line signals.
Signal Interfaces and Connectors
The DS200TCQAG1A uses multiple connectors to exchange signals and power with other boards and terminal boards.
| Connector | Function |
|---|---|
| 2PL | Distributes TCPS board power to the R1, R2, and R3 cores. |
| 3PL | Provides the data bus connection between the STCA and TCQA boards in R2 and R3, and between the STCA, TCQA, and TCQE boards in R1. Conditioned signals transfer to the COREBUS through this connector. |
| JA | Carries thermocouple inputs and cold junction compensation signals from the TBQA terminal board for R1, R2, and R3 cores. |
| JB | Transfers 4-20 mA input and output signals through the JBR terminal board connector on the TBQC. |
| JD | Carries trip signals from the R1 core to the TCTG board in the P1 core. This connector is not used in R2 or R3. |
| JE | Transfers servo valve driver outputs, relay driver outputs, generator and line signals, and pulse signals. Power supply monitor inputs are also carried through this interface. |
| JF | Carries LVDT/LVDR position feedback inputs from the JFR terminal board connector on the TBQC. |
| JG | Carries vibration inputs from the JG terminal board connector on the TBQB, together with +/-10 VDC inputs. |

Application and Configuration Notes
The DS200TCQAG1A performs signal conditioning within the Mark V I/O architecture. Its connector assignments determine how it exchanges signals with terminal boards and other control boards.
Meanwhile, the JD connector has a specific role in the R1 core and does not serve the same function in R2 or R3. Therefore, maintenance personnel should check the installed I/O core and connector arrangement before replacing the board.
Frequently Asked Questions
Q: What is the main function of the DS200TCQAG1A?
A: It scales and conditions analog signals received from terminal boards and transfers conditioned signals to the COREBUS. It also handles several feedback, control, and monitoring signal types.
Q: Which Mark V I/O cores use the DS200TCQAG1A?
A: The board is described for use in the R1, R2, and R3 I/O cores. However, the JD connector is used only in R1 for carrying trip signals to the TCTG board.
Q: What is the difference between the JA, JB, and JG connectors?
A: JA carries thermocouple inputs and cold junction compensation signals. JB handles 4-20 mA signals, while JG carries vibration inputs and +/-10 VDC signals.
