GE DS200SDCCG4RGD Turbine Control Board | Mark VI Series

GE DS200SDCCG4RGD Turbine Control Board – Mark VI Series

When a turbine control board fails mid-operation, the consequences extend far beyond a simple equipment stoppage. Gas and steam turbines powering utilities, petrochemical plants, and industrial facilities can trip unexpectedly, triggering cascading shutdowns, production losses measured in tens of thousands of dollars per hour, and safety incidents that demand immediate regulatory attention. The DS200SDCCG4RGD is the precise component that stands between controlled operation and unplanned downtime — a board that cannot be substituted with a generic alternative without risking system instability.

Within GE’s Mark VI Turbine Control System family, the DS200SDCCG4RGD occupies a critical position as a Speed/Dynamics Control Card (SDCC). The Mark VI platform is GE’s flagship distributed turbine control architecture, deployed across hundreds of power generation and industrial facilities worldwide. This specific revision (G4RGD) represents a mature, field-proven hardware iteration engineered for high-reliability environments where mean time between failures (MTBF) is a non-negotiable specification. Its global installed base makes it one of the most sought-after spare parts in the power generation MRO market.

Key Features & Benefits

• Speed Signal Processing: Dedicated hardware for real-time turbine speed acquisition and dynamics computation, ensuring sub-millisecond response to speed deviations.
• Triple Modular Redundancy (TMR) Compatible: Designed to operate within GE’s TMR architecture, enabling fault-tolerant control without process interruption.
• Proven Field Reliability: The G4RGD revision incorporates component-level improvements over earlier SDCC revisions, reducing susceptibility to thermal cycling failures common in turbine enclosures.
• Direct Drop-In Replacement: Maintains full backward compatibility with existing Mark VI panel wiring and I/O termination boards — no firmware reconfiguration required in most applications.
• Reduced Commissioning Risk: Sourcing an OEM-equivalent board eliminates the integration risk associated with third-party alternatives or field-modified cards.

Industry & Equipment Applications

• Power Generation: Gas turbine generators (Frame 6, Frame 7, Frame 9 series), steam turbines in combined-cycle and coal-fired plants.
• Oil & Gas: Mechanical drive turbines for compressor trains on LNG, pipeline, and offshore platforms.
• Petrochemical & Refining: Process-critical turbine-driven pumps and compressors where continuous availability is mandatory.
• Pulp & Paper / Steel: Industrial steam turbines driving large rotating equipment in continuous-process manufacturing.
• Independent Power Producers (IPPs): Peaker plants and cogeneration facilities requiring rapid spare parts sourcing to minimize revenue loss during outages.

Frequently Asked Questions

Q: Is the DS200SDCCG4RGD compatible with both TMR and Simplex Mark VI configurations?
A: Yes. The SDCC board is designed for use in both Triple Modular Redundancy (TMR) and Simplex Mark VI panel configurations. Please confirm your panel type when inquiring so we can verify the exact revision requirements.

Q: What is the difference between DS200SDCCG4RGD and other SDCC revisions such as G1 or G3?
A: Revision suffixes (G1, G3, G4) reflect incremental hardware changes made by GE during the product lifecycle, typically addressing component obsolescence or reliability improvements. The G4RGD revision is generally considered a later, more refined iteration. Cross-revision compatibility should be confirmed with your GE service documentation or our technical team.

Q: Do you provide a warranty on this board?
A: Warranty terms vary by unit condition (new surplus vs. refurbished). Please request warranty details when submitting your inquiry. All units are inspected before shipment.

Q: Can you ship to my country?
A: Konmask.com ships internationally via DHL, FedEx, and UPS. We serve customers across Asia, Europe, the Middle East, Africa, and the Americas. Export compliance documentation is available upon request.

Q: How long does it take to receive a quote?
