GE DS200TCQRG1RFC Turbine Control Qualification Relay Board – Mark VI Series
When a gas turbine’s control relay board fails mid-operation, the consequences cascade instantly: protective relay logic drops out, turbine trip circuits lose integrity, and the entire power generation unit faces an unplanned shutdown. In energy plants, petrochemical facilities, and industrial co-generation sites, every unplanned outage translates directly into lost megawatts, regulatory scrutiny, and six-figure recovery costs. The GE DS200TCQRG1RFC is the precision relay interface board that keeps these scenarios from becoming reality — a mission-critical component that no Mark VI-based turbine control system can afford to run without.
Within the GE Mark VI Turbine Control System family, the DS200TCQRG1RFC occupies a specialized role as the TCQR (Turbine Control Qualification Relay) board. It serves as the hardwired relay output interface between the Mark VI’s digital control logic and the physical trip/protection circuits of the turbine. Globally, the Mark VI platform controls thousands of GE Frame 5, Frame 6, Frame 7, and Frame 9 gas turbines across power utilities, oil & gas pipelines, and LNG terminals — making the DS200TCQRG1RFC one of the most strategically important spare parts in any plant’s critical spares inventory.

Frequently Asked Questions
Q: Is the DS200TCQRG1RFC compatible with both Mark V and Mark VI systems?
A: The DS200TCQRG1RFC is specifically designed for the GE Mark VI platform. While some DS200-series boards have cross-compatibility, this part number is Mark VI-specific. Please confirm your panel model (VCMI/VCRC/VCCC) before ordering.
Q: What does “G1RFC” in the part number suffix mean?
A: GE uses alphanumeric suffixes to denote hardware revision levels and configuration variants. “G1RFC” indicates a specific revision of the TCQR board. Always match the full part number including suffix when ordering replacements.
Q: Can you supply a tested unit with a warranty?
A: Yes. Tested and refurbished units come with a 90-day functional warranty. New surplus units are sold as-is with visual inspection certification. Contact us to specify your requirement.
Q: How long does international shipping take?
A: Standard express shipping (DHL/FedEx) typically takes 3–7 business days to most destinations. Expedited options are available for urgent requirements.
Q: Do you provide export documentation for customs clearance?
A: Yes. We provide commercial invoice, packing list, and certificate of origin. HS code classification guidance is available upon request based on your destination country’s requirements.
Q: What if the board I receive doesn’t resolve my turbine fault?
A: Our technical team can assist with Mark VI fault diagnostics. If the board is confirmed non-faulty after testing, we offer exchange or return per our warranty policy.
