Product Introduction
The GE DS200QTBAG1ADC is a specialized termination circuit board designed specifically for the Speedtronic Mark V gas and steam turbine control architecture. Operating as a Contact Output Termination Board (QTBA), it serves as a critical interface hub for routing and switching heavy-duty discrete outputs, alarm signals, and trip solenoids between the core rack processor controllers and external plant actuators.
The board provides reliable signal isolation, transient suppression, and secure physical termination for multi-conductor field wiring, ensuring dependable operation in demanding power-generation environments.

Compliance & Standards Alignment
- Designed and manufactured in strict compliance with heavy industrial electrical specifications for power generation, turbine management, and critical control protection networks.
- Treated with standard industrial PCB conformal coating to resist ambient moisture, airborne dust, and chemical degradation inside terminal compartment cabinets.
Technical Note: When servicing or wiring output loops on the QTBA board, verify external power source voltages and fuse ratings carefully against plant drawings to prevent overcurrent conditions on internal relay contacts.
Storage & Asset Preservation Guidelines
- Store the termination circuit board hermetically sealed inside its original metallized anti-static (ESD) shielding bag to protect mounted logic components and connector pins from static discharge.
- Maintain warehouse storage environments where relative humidity is strictly kept below 60% to prevent terminal block and pin oxidation.
- Avoid mechanical stacking or heavy pressure on the board to prevent physical damage to terminal housings or structural board flexing.
Physical Installation Prerequisites
- Ensure that all external power feeds, output loops, 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 termination cabinet using all specified mounting hardware to maintain structural ground continuity.
- 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: What does the “ADC” suffix designate on this QTBA part number?
A: The suffix reflects the hardware grouping (G1), major revision tier (A), and specific artwork/component layout revisions (DC). Always cross-reference your system’s panel bill of materials (BOM) 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.
