GE DS200TCQAG1BGE Analog Input I/O Board

GE DS200TCQAG1BGE Analog Input I/O Board

The GE DS200TCQAG1BGE, also cataloged as the TCQA Analog Input I/O Board, serves as a dedicated hardware component for analog signal acquisition and conditioning within the Mark V turbine control system.

Hardware Specifications

Backplane Bus Communication and I/O Density Scaling

The DS200TCQAG1BGE integrates with the Mark V backplane bus, supporting deterministic communication velocity across turbine supervisory modules. I/O density scaling is achieved through multiple dedicated circuits: 4-20 mA input/output, thermocouple, RTD, LVDT/R, seismic vibration, and generator/line monitoring. Ribbon cable routing is critical; cables must be separated from high-voltage conductors to prevent interference. Firmware flash compatibility ensures synchronization with evolving I/O configuration constants.

Frequently Asked Questions (FAQ)

Q: Are all product revisions of DS200TCQAG1BGE backwards-compatible? A: No. Only the first two functional revisions are backwards-compatible; artwork revision E is unique to this board.

Q: Where was the DS200TCQAG1BGE manufactured? A: It was manufactured at GE’s Salem, Virginia facility.

Q: What is the role of the diagnostic LEDs? A: The six LEDs provide real-time indication of normal drive conditions and functional faults for troubleshooting.

Field Installation Guidelines

• Install the board in designated Mark V rack slots with full connector engagement.
• Route ribbon cables exactly as originally installed to avoid stress on fine conductors.
• Disconnect and reconnect ribbon cables by holding the plastic connector, not the cable itself.
• Ensure shielded wiring for analog signals is grounded at the rack end only.
• Verify jumper settings (J1, JP2, JP3) before commissioning to align with system requirements.
