GE DS200DDTBG1A
Product Introduction
The is a critical core component within the Mark VIe turbine control ecosystem. Acting as the central processing and communication hub, it houses the main processor and redundant Ethernet drivers necessary to coordinate high-speed I/O packs via the dedicated IONet. This board is engineered to handle the deterministic, real-time demands of steam and gas turbine protection and control, ensuring bumpless transfer in redundant configurations.
Field engineers specify the because it provides the essential bridge between the operator station and the field I/O, maintaining data integrity at 100 Mbps even in electrically noisy power generation environments. Its QNX-based architecture guarantees the microsecond-level response times required for critical turbine safety logic.
Key Selling Points & Differentiators
- Mark VIe Core Compatibility: Designed specifically as a core board for GE Mark VIe systems; not recommended for Mark V or non-GE platforms due to proprietary IONet protocols.
- High-Speed IONet Communication: Provides deterministic 100 Mbps full-duplex communication with I/O packs, supporting cycle rates as fast as 10ms for critical control loops.
- Flexible Redundancy Architecture: Supports single, dual, and triple modular redundancy (TMR) configurations, allowing seamless failover without process interruption.
- Rigorous Live Bench Testing: Every unit undergoes a 24-hour continuous load test with IONet communication verification and processor stress testing before shipping.
- New Surplus Availability: Factory-sealed condition with verified source traceability, bypassing typical OEM lead times for discontinued Mark VIe hardware.
- Anti-Counterfeit Verification: Serial numbers are checked against manufacturer databases during incoming inspection to guarantee authenticity.

FAQ
No. The is designed exclusively for the Mark VIe platform. Mark V systems use different core boards (e.g., DS200TCQBG1A) and do not support the IONet architecture. Always verify your system generation before ordering.
I have a DS200DDTBG1B on hand. Can I use it as a direct replacement?
The suffix (G1A vs. G1B) often indicates hardware revision, firmware version, or specific IONet port configuration (e.g., fiber vs. copper). While they may be functionally similar, mixing revisions in a redundant pair can cause synchronization faults. Always match the exact suffix or consult the Mark VIe hardware manual for approved substitutions.
Do I need to configure the IONet address before installing?
Yes. The board requires configuration of its IONet node address and redundancy role via ToolboxST software. I always recommend backing up your Mark VIe configuration, verifying the node ID matches your system design, and running a network diagnostic after installation to confirm communication with all I/O packs.
What happens if this board fails in a TMR configuration?
In a properly configured TMR system, the remaining two boards will continue to control the turbine with bumpless transfer. The failed board will be automatically voted out, and an alarm will be generated for immediate replacement. However, this assumes the other two boards are healthy and the voting logic is correctly configured.
Is there a warranty on this new surplus unit?
Yes. All new surplus modules come with a standard 12-month functional warranty. If the unit fails during normal operation within that period, we provide a direct replacement. We also include our internal test report with every shipment so you can verify the 24-hour load test and IONet communication results before installation.
