4. Product Introduction (Anti-Template)
The DS200TBQCG1AAA is an Analog Termination Module (TBQC) used in GE Mark V Speedtronic turbine control systems. It serves as the field termination point for milliamp-level analog signals and LVDT/R position feedback.
The board provides two high-density terminal blocks for landing field wiring and routes the signals to the associated TCQA board in the core via ribbon connectors. It supports 4–20 mA inputs, higher-range milliamp outputs, and LVDT position inputs. Fifteen jumpers allow configuration of signal grounding and routing. The module is a critical interface between field instruments (pressure, flow, position sensors, etc.) and the Mark V control processors, ensuring clean signal transfer into the control system.

5. QC, Procurement & Logistics SOP
- Inbound Verification – Confirm full part number (DS200TBQCG1AAA), revision markings, terminal block condition, and connector integrity. Photograph all labels.
- Live Rig Testing – Install in a compatible Mark V core or test setup, verify power and basic connectivity to the TCQA board, and check signal path continuity where possible.
- QA & Packaging – After inspection, protect all connectors and terminal blocks, clean the board, and pack in anti-static protective packaging with desiccant.
- Global Logistics & Export Compliance – Classify under the correct HS code for industrial control circuit boards. Packaging must protect against electrostatic discharge and mechanical shock; export documentation is prepared to minimize customs delays.
6. Technical Pitfalls & Integration Warnings
TCQA Pairing – The TBQC must be correctly cabled to its associated TCQA board. Incorrect or damaged ribbon cables will prevent signal transfer.
Jumper Configuration – The 15 jumpers (BJ1–BJ15 and others) control signal grounding and routing. Incorrect jumper settings can cause open inputs or ground loops.
Signal Type Matching – The board is designed for specific milliamp and LVDT signals. Connecting incorrect signal types or voltage levels can damage the board or the TCQA.
Terminal Torque – Over-tightening or under-tightening field terminals can lead to intermittent connections or damaged terminal blocks in a high-vibration turbine environment.
7. Frequently Asked Questions (FAQ)
What is the realistic global lead time for a verified DS200TBQCG1AAA?
As a legacy Mark V board, availability depends on surplus stock. Typical lead time after verification is 3–12 business days plus standard air freight.
What is the function of the DS200TBQCG1AAA?
It is the Analog Input Milliamp I/O Termination Module (TBQC) that lands 4–20 mA, higher milliamp, and LVDT signals for the Mark V system.
What board does it connect to?
It interfaces primarily with the TCQA board in the Mark V core.
What signals does it handle?
Milliamp inputs and outputs (including 4–20 mA) and LVDT/R position inputs.
Is it still in production?
No. Mark V boards are discontinued by GE and are now supplied through surplus and repair channels.
How many terminal points does it have?
Two terminal blocks with 83 terminals each.
What should be confirmed before ordering a replacement?
Exact part number including the full revision suffix (G1AAA), compatibility with the existing TCQA board, and the required jumper configuration.
