Product Introduction
The GE DS200TCEBG1BAA is a specialized printed circuit board engineered for the Speedtronic Mark V turbine control system architecture. Operating in the role of a Protective Termination Expander Board (TCEB), it expands termination capacity for critical protective loops, emergency overspeed detection, flame sensing, and common relay circuits.
Equipped with high-compatibility signal transformers and multiple interface connectors, the board ensures precise, noise-resistant signal routing between field termination modules and core processor cards, sustaining high reliability in power generation and heavy industrial turbine management.

Compliance & Standards Alignment
- Designed and manufactured in accordance with heavy industrial electrical specifications for power generation and turbine automation.
- Features standard factory PCB conformal coating to resist atmospheric moisture and chemical degradation within industrial control cabinets.
Technical Note: When disconnecting or re-routing internal 20-pin ribbon cables during maintenance, carefully label each cable to prevent misconnection, and avoid laying ribbon harnesses parallel to high-voltage power feeds to minimize induced electrical noise.
Storage & Asset Preservation Guidelines
- Store the circuit board hermetically sealed inside its original metallized anti-static (ESD) shielding bag to protect sensitive onboard logic chips and transformers from static discharge.
- Maintain warehouse storage conditions with relative humidity strictly below 60% to prevent terminal corrosion on edge connectors.
- Avoid mechanical stacking or heavy pressure on the board enclosure to prevent flexure damage to the printed circuit substrate.
Physical Installation Prerequisites
- Ensure that all rack power supplies and associated turbine control cabinet feeds are completely de-energized and locked out (LOTO) prior to handling or replacement.
- Mount the board securely into its designated VME rack slot within the Mark V control core, verifying clean engagement of backplane pins.
- Inspect all plug-in connectors and pin headers for particulate debris or bending prior to sliding the card into position.
Buyer’s FAQ & Logistics
Q: What Harmonized System (HS) code applies to this Mark V turbine control board?
A: Industrial electronic control system printed circuit assemblies and processor parts typically classify under HS code 8538.90 (parts suitable for use solely or principally with control apparatus). Confirm final categorization parameters with your licensed customs broker.
Q: Is the DS200TCEBG1BAA backward compatible with older Mark V revisions?
A: The “G1BAA” suffix denotes specific functional and artwork revision levels building upon the parent DS200TCEB design. Verify your system software version and hardware BOM compatibility prior to procurement.
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.
