Product Introduction
The GE DS200DTBCG1AAA is a specialized termination circuit board engineered for the Speedtronic Mark V gas and steam turbine control system architecture. Functioning as a Digital/Drive Termination Board (DTBC), it provides an essential interconnection bridge for high-density digital I/O, auxiliary control loops, or drive-related status signals between field devices and the main control processor core.
The board ensures robust signal conditioning, transient suppression, and terminal security, allowing external auxiliary cabling to interface cleanly with internal rack-mounted processor and I/O cards.

Compliance & Standards Alignment
- Designed and manufactured in strict compliance with heavy industrial electrical specifications for power generation, turbine management, and heavy auxiliary control networks.
- Factory-treated with standard industrial PCB conformal coating to resist atmospheric moisture, dust, and corrosive agents inside terminal and drive cabinets.
Technical Note: Always verify control voltage levels, auxiliary circuit designations, and signal polarities against plant engineering drawings before landing external field conductors onto the DTBC barrier terminal strips.
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 external auxiliary power feeds, digital I/O 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 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 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 DS200DTBCG1AAA interchangeable with earlier DTB or DTBC 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 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.
