Product Introduction
The GE DS200DTBAG1AAA is a specialized printed circuit board utilized within the Speedtronic Mark V gas and steam turbine control system. Functioning as a Drive Termination Board (DTBA), it serves as the primary electrical interface and wiring bridge for low-voltage excitation, auxiliary motor controls, or static starter drive signals linked to the turbine auxiliary systems.
The board provides robust signal conditioning, transient suppression, and terminal connections to route critical motor/drive status feedback and control commands securely between field devices and the main control processor core.

Compliance & Standards Alignment
- Designed and manufactured in strict compliance with heavy industrial electrical specifications for power generation and large rotating equipment auxiliaries.
- Factory-treated with standard PCB conformal coating to resist humidity, airborne contaminants, and corrosive agents inside industrial control and drive cabinets.
Technical Note: Always verify control voltage levels and auxiliary circuit designations against plant schematics before landing field conductors onto the barrier terminal strips to prevent accidental feedback loops.
Storage & Asset Preservation Guidelines
- Store the termination circuit board hermetically sealed inside its original metallized anti-static (ESD) shielding bag to protect surface-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 external auxiliary power feeds, drive circuits, 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 panel ground continuity.
- Verify that terminal screws are securely torqued down on conductors to prevent high-resistance connections or vibration-induced loosening under heavy industrial operating conditions.
Buyer’s FAQ & Logistics
Q: What Harmonized System (HS) code applies to this Mark V drive termination board?
A: Industrial electronic control system printed circuit assemblies and control panel parts 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 DS200DTBAG1AAA interchangeable with any DTB variant?
A: Revision suffixes (such as “G1AAA”) denote specific hardware layout and component iterations. Verify your system’s BOM compatibility and drawing packages before substituting board variants.
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.
