Product Introduction
The GE DS200DTBBG1ABB is a specialized termination circuit board engineered for the Speedtronic Mark V gas and steam turbine control architecture. Operating as a Digital Termination Board (DTBB), it provides an essential interconnection and signal-routing bridge for discrete inputs, digital control signals, and auxiliary status lines between field-mounted instrumentation and the core rack processor modules.
The board is populated with durable barrier terminal strips, onboard resistor networks (such as SIP arrays), and secure multi-pin headers, ensuring clean transition, transient suppression, and high signal integrity across demanding power-generation environments.

Compliance & Standards Alignment
- Designed and manufactured in strict compliance with heavy industrial electrical specifications for power generation, turbine management, and auxiliary control networks.
- Factory-treated with standard industrial PCB conformal coating to resist atmospheric moisture, airborne dust, and corrosive agents inside terminal compartment cabinets.
Technical Note: When mapping or replacing field wires on the DTBB termination board, meticulously verify control signal designations and pin orientations against plant installation drawings to prevent logic input errors.
Storage & Asset Preservation Guidelines
- Store the 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 auxiliary power feeds, digital I/O loops, and cabinet interfaces are completely de-energized and locked out (LOTO) prior to handling, wiring, or card 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 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 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 DS200DTBBG1ABB interchangeable with earlier DTB layout revisions?
A: Revision suffixes (such as “G1ABB”) 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.
