Functional Description

DS200TCQCG1AEB is an Analog I/O Expander Board developed by GE. It is a part of Mark V Series. It is designed to scale and condition analog signals, enhancing the overall system's ability to process inputs from terminal boards across the I/O cores. This expansion board provides additional signal processing capabilities, supporting functions like shaft speed monitoring, fuel flow signals, and power signal conditioning.

Key Functions

• Scaling and Conditioning: It processes analog signals, ensuring they are in a usable format for further system processing.
• LVDT and LVDR Excitation: Provides the necessary excitation for LVDT and LVDR sensors, which are critical for measuring displacement in turbine systems.
• Signal Communication: The board communicates with other core modules like the STCA and TCQA boards via I/O connectors, ensuring data flow throughout the system.

Connector Details

• 2PL: Distributes power from the TCPS power supply board located in the R1, R2, and R3 cores.
• 8PL: Serves as the I/O connector to the STCA boards in the R1, R2, and R3 cores. It handles signals like RS232 outputs, serial I/O, AC/DC power monitoring signals, and pulse rate magnetic pickup signals.
• 19PL: Provides an I/O connection to the STCA board and carries signals such as megawatt, generator, bus, and compressor stall detection signals. It also carries pulse rate signals from the high-pressure shaft.
• JC: Connected to the TCPS power supply board, passing necessary power supply signals through the TCQC board to the TCQA board and STCA board via JE and 19PL connectors.
• JE: Facilitates the transfer of power supply monitoring signals to the TCQA board, and reads servo valve outputs and generator line signals.
• JFF: Writes servo outputs to the QTBA terminal board.
• JGG: Manages servo outputs and 15-amp signals, along with reading magnetic pickup and megawatt transducer signals.
• JH: Reads pulse rate and compressor stall signals from the TBQB terminal board.
• JJ: Reads speed signals from the TCQE board in the R1 core, which originate from the PTBA terminal board in the P1 core.
• JX: Terminates the IONET signal from the TCEA board in the P1 core, used specifically in the R1 core.

Configuration and Hardware Settings

• Jumpers 1-16: These control the output current range for the servo outputs, with even-numbered jumpers handling feedback scaling and odd-numbered jumpers controlling the source output resistance.
• Jumpers 25-36: These jumpers add additional feedback scaling options for servos 1 through 4, providing a maximum current range of ±240 mA.
• BJ17: This jumper sets the RS232 port for card testing.
• BJ21: Enables the stall timer function.
• BJ22: Activates the oscillator for factory testing.
• BJ18 and BJ20: These jumpers limit the P15 and N15 current values.

Frequently Asked Questions

What is DS200TCQCG1AEB?
It is an Analog I/O Expander Board developed by GE.

What types of signals does the board handle?
The board processes signals from megawatt transducers, high-pressure shaft speed, liquid fuel flow, and other analog signals. It also handles pulse rate signals from sensors like the high-pressure shaft and transfers them to other boards in the system.

How does the board communicate with other modules?
The board communicates with other modules like the STCA board and TCQA board via I/O connectors such as the 19PL and JE. It ensures the proper scaling and conditioning of signals, which are then processed by other components for turbine control.

How do I configure the board?
The board is configured using hardware jumpers. Jumpers 1-16 adjust the output current range for servo outputs, and jumpers 25-36 provide additional feedback scaling options. There are also jumpers for enabling features like RS232 port testing, the stall timer, and factory test oscillators.

What is the purpose of the 19PL connector?
The 19PL connector carries a wide variety of signals, including megawatt, generator, bus, compressor stall detection, and high-pressure shaft pulse rate signals. It also carries power bus and neutral bus signals, facilitating communication between the TCQC board and other components such as the STCA board.
