GE DS200SDCCGSAHD – Digital I/O Board | Mark VI Turbine Control Platform
Engineering Background
The DS200SDCCGSAHD is a Digital I/O Board designed and manufactured by GE (General Electric) as part of the Mark VI turbine control system architecture. The Mark VI platform is GE’s industry-standard distributed control solution for gas turbines, steam turbines, and combined-cycle power generation units worldwide. This board serves as the primary interface layer between field-level discrete signals and the Mark VI controller backplane, enabling deterministic, high-integrity I/O processing in safety-critical environments.
Product Positioning
Procurement engineers sourcing replacement or spare DS200SDCCGSAHD boards require a supplier who can verify authenticity, confirm firmware compatibility, and ship with full traceability documentation. Konmask.com specializes in exactly this: verified surplus and new-surplus GE Mark VI components with engineering-grade quality assurance and rapid global dispatch.

Engineering Advantages
- Deterministic I/O Scanning: Designed for the Mark VI’s real-time control loop, ensuring sub-millisecond discrete signal response times critical for turbine protection logic.
- High Channel Density: Consolidates multiple discrete I/O points on a single board, reducing rack space and wiring complexity in retrofit projects.
- Robust Isolation: Optical isolation on I/O channels protects the controller backplane from field-side transients and ground loops common in power generation environments.
- Hot-Swap Compatible: Supports live replacement procedures within Mark VI redundant configurations, minimizing planned outage windows.
- Proven MTBF: GE Mark VI boards are rated for continuous 24/7 operation in Class I, Division 2 hazardous area environments.
System Architecture & Signal Flow
Within the Mark VI architecture, the DS200SDCCGSAHD occupies the I/O module slot in the VCMI or VTUR controller rack. Field wiring from terminal boards (e.g., TBCI, TBQC) connects to the board’s input/output connectors. The board conditions and digitizes discrete signals, then passes structured data across the VME-based backplane to the main processor (VCMI) for execution of turbine control algorithms. Output channels drive relay coils, solenoid valves, and annunciator panels based on controller logic outputs. In TMR (Triple Modular Redundant) configurations, three DS200SDCCGSAHD boards operate in parallel with voted outputs, ensuring fail-safe operation.
Sourcing & Quality Verification
- Visual Inspection: All boards inspected for physical damage, burnt components, corrosion, and connector integrity before listing.

Technical FAQ
Q: Is the DS200SDCCGSAHD compatible with both Mark VI and Mark VIe systems?
A: The board is native to the Mark VI platform. Compatibility with Mark VIe depends on the specific rack configuration and firmware revision. Contact our engineering team with your system details for confirmation.
Q: Can you supply a specific hardware revision (e.g., Rev. H)?
A: We document revision levels for all stock. Specify your required revision at inquiry and we will confirm availability or advise on cross-compatible alternatives.
Q: What is the lead time for urgent outage requirements?
A: In-stock units can ship same day or next business day. Express international delivery typically 2–5 business days depending on destination.
Q: Do you provide a Certificate of Conformance (CoC)?
A: Yes. A Konmask CoC is provided with every shipment. OEM CoC documentation is included where available from the original decommission source.
Q: Can I return the board if it does not fit my application?
A: Yes, within 30 days of receipt in original condition. Contact [email protected] to initiate an RMA.
