Functional Description

DS200TCQAG1ABA is an Analog IO Board developed by GE. It is a part of the Mark V control system. The Analog IO Board plays a role in the Mark VIe system by scaling and conditioning a variety of analog signals received from terminal boards mounted on the I/O cores R1, R2, and R3. These signals are essential for monitoring and controlling various aspects of turbine operations. 

Signal Types Handled

• LVDT Inputs: Used for measuring position or displacement.
• Servo Valve Outputs: Control valves that regulate fluid flow within the turbine.
• Thermocouple Inputs: Measure temperature using thermocouples placed at critical points.
• 4-20 mA Inputs and Outputs: Commonly used for transmitting process control signals.
• Vibration Inputs: Monitor turbine vibration levels for predictive maintenance.
• Relay Driver Outputs: Control relays for switching operations.
• Pulse Inputs: Capture digital signals such as speed or frequency.
• Voltage Inputs: Measure electrical potentials for monitoring purposes.
• Generator and Line Signals: Signals exchanged with other boards for synchronization and monitoring purposes.

Integration with Other Boards

• Some signals processed by the TCQA board are written to the STCA board via the 3PL connector. This integration ensures that critical analog data is communicated effectively within the control system, facilitating real-time monitoring and control.
• Generator and line signals are exchanged with the TCQC board via the JE connector, enabling synchronization and coordination between different components of the turbine control system.

Specific Signal Conditioning

• Signals such as 4-20 mA inputs, including fuel flow pressure and compressor stall-detect signals, undergo scaling and conditioning on the TCQA board. This process ensures that these signals are accurately represented and compatible with the system's operational requirements.
