GE DS200TBQCG1AAA Analog Input Termination Module

GE DS200TBQCG1AAA Analog Input Termination Module

The GE DS200TBQCG1AAA, also cataloged as the TBQC Analog Input Termination Module, operates as a dedicated hardware interface for analog input and output signal routing within Mark V turbine control system cores.

Hardware Specifications

Backplane Bus Communication and I/O Density Scaling

The TBQC module integrates with the Mark V backplane bus, ensuring deterministic communication velocity between terminal boards and the TCQA processor. I/O density scaling is achieved through dual-function connections such as JBR, which simultaneously writes 4-20 mA inputs and reads mA outputs. Jumper-selectable output current ranges (20 mA or 200 mA) provide flexibility for diverse instrumentation requirements, while unused ports (JBS/T, JFS/T, TEST) remain reserved for diagnostic or expansion scenarios.

Frequently Asked Questions (FAQ)

Q: What signals does the JBR connection handle? A: JBR writes 4-20 mA input signals to the TCQA board and reads mA output signals, enabling monitoring and feedback functions.

Q: What is the role of the JFR connection? A: JFR transmits LVDT/R position input signals to the TCQA board, supporting precise position sensing and control.

Q: How are output currents configured? A: Hardware jumpers on the TBQC board allow selection between 20 mA and 200 mA maximum output ranges.

Field Installation Guidelines

• Install the module at position 9 in the designated core (R1, R2, or R3).
• Ensure shielded wiring for 4-20 mA and LVDT/R inputs is grounded at the rack end only.
• Route analog signal cabling separately from high-voltage conductors to minimize interference.
• Verify jumper settings before energizing the system to ensure correct output current configuration.
• Inspect connector seating (JBR, JFR) to confirm proper engagement with TCQA board interfaces.
