Product Introduction
The GE DS200TBQBG1ACB is a precision-engineered printed circuit board designed specifically for the Speedtronic Mark V gas and steam turbine control architecture. Operating as an RST Analog Termination Board (TBQB), it serves as a robust wiring transition hub that bridges field instrumentation loops with downstream core analog processing cards (such as the TCQA or TCCA boards).
The board is engineered to receive, filter, and route critical low-level analog signals—including pressure, temperature, flow rates, and valve positioning feedback—while maintaining high noise rejection and signal stability across complex power-generation environments.

Compliance & Standards Alignment
- Designed and manufactured in strict compliance with heavy industrial electrical specifications for power generation and large rotating machinery management.
- Treated with a standard industrial PCB conformal coating to resist ambient moisture, dust, and chemical degradation inside terminal compartment cabinets.
Technical Note: When landing field wires onto the TBQB board, ensure that analog signal shields are properly terminated to designated ground studs to prevent electromagnetic interference (EMI) loop errors in precision thermocouple or 4–20 mA circuits.
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 multi-pin connector headers from static discharge.
- Maintain warehouse storage environments where relative humidity is strictly kept below 60% to prevent terminal oxidation.
- Avoid mechanical stacking or heavy physical pressure on the board to prevent structural damage to the terminal block housings or multi-layer printed circuit substrate.
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 hardware to maintain structural ground bonding.
- Verify that all terminal block 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: What does the “ACB” suffix designate on this TBQB part number?
A: The suffix reflects the hardware grouping (G1), major revision tier (A), and specific artwork/component layout revisions (CB). Always cross-reference your system’s panel bill of materials (BOM) before substituting 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.
