Product Introduction
The GE DS200TBQCG1AAA is a specialized termination circuit board designed for the Speedtronic Mark V gas and steam turbine control architecture. Functioning as an RST Analog Input/Output Termination Board (TBQC), it acts as a critical signal transition and wiring hub for analog instrumentation loops, mA input/output channels, and transducer feeds.
The board interfaces directly with field wiring, suppresses electrical transients, and securely routes conditioned signals to downstream core analog processor cards (such as the TCQA or TCCA boards) via multi-pin ribbon cables, ensuring measurement stability across heavy industrial turbine management systems.

Compliance & Standards Alignment
- Designed and manufactured in strict compliance with heavy industrial electrical specifications for power generation and turbine automation environments.
- Treated with a standard industrial PCB conformal coating to resist humidity, airborne particulates, and chemical degradation inside terminal compartment cabinets.
Technical Note: When servicing or replacing termination boards, meticulously map and label each incoming field wire to prevent wiring offset errors that could distort analog calibration loops.
Storage & Asset Preservation Guidelines
- Store the termination circuit board hermetically sealed inside its original metallized anti-static (ESD) shielding bag to protect mounted components and connector pins from static discharge and oxidation.
- Maintain warehouse storage environments where relative humidity is strictly kept below 60%.
- Avoid mechanical stacking or heavy pressure on the board to prevent physical damage to terminal block housings or structural board flexing.
Physical Installation Prerequisites
- Ensure that all field sensor loops, power feeds, and cabinet interfaces are completely de-energized and locked out (LOTO) prior to handling, wiring, or replacement.
- Mount the board securely onto the designated sub-panel within the Mark V core termination cabinet using all specified mounting hardware to maintain structural ground bonding.
- Verify that terminal screws are properly torqued down on incoming conductors to prevent high-resistance connections or vibration-induced loosening under heavy industrial conditions.
Buyer’s FAQ & Logistics
Q: What Harmonized System (HS) code applies to this Mark V termination board?
A: Industrial electronic control system printed circuit assemblies and control panel components typically classify under HS code 8538.90 (parts suitable for use solely or principally with control apparatus). Confirm final classification parameters with your licensed customs broker.
Q: Is the DS200TBQCG1AAA interchangeable with earlier TBQ variants?
A: Revision suffixes (such as “G1AAA”) denote specific hardware layout, component spacing, and circuit revisions. Verify your system’s BOM compatibility and panel documentation before substituting alternative board versions.
Q: Is the listed online price final for procurement?
A: Note: Price is subject to market conditions and available surplus inventory levels; contact our technical sales desk for a formal, time-sensitive quotation.
