GE DS200TCERG2BTF Emergency Overspeed Protection – Mark VI Turbine Control Series
When a gas turbine exceeds its rated speed threshold without a functioning overspeed protection circuit, the consequences are catastrophic — uncontrolled rotor acceleration, mechanical failure, and potential plant-wide shutdown. In critical power generation and industrial turbine environments, a single failed overspeed board can halt an entire facility, costing operators tens of thousands of dollars per hour in lost production. The GE DS200TCERG2BTF Emergency Overspeed Board is the dedicated hardware safeguard that stands between normal operation and disaster, providing the hardwired, fail-safe trip logic that software alone cannot guarantee.
The DS200TCERG2BTF occupies a specialized and non-negotiable role within GE’s Mark VI Turbine Control System — one of the most widely deployed distributed control architectures in global power generation. As the emergency overspeed module, it operates independently of the main control processor, ensuring that overspeed trip signals are executed even in the event of a primary controller fault. This design philosophy reflects GE’s commitment to SIL-rated safety integrity in turbine protection, making the DS200TCERG2BTF a cornerstone component in gas turbine, steam turbine, and combined-cycle power plant installations worldwide.

Frequently Asked Questions
Q: What is the difference between DS200TCERG2BTF and DS200TCEAG1B?
A: Both are GE Mark VI emergency protection boards, but they serve different functions within the protection chain. The TCERG2BTF is specifically the Emergency Overspeed Board, while the TCEAG1B is the Emergency Trip Board. They are complementary, not interchangeable. Always verify your turbine’s Bill of Materials before ordering.
Q: Can DS200TCERG2BTF be used in Mark V systems?
A: No. The DS200TCERG2BTF is designed for the Mark VI platform. Mark V systems use a different board architecture and connector standard. Contact us if you need the Mark V equivalent.
Q: Do you offer exchange or repair services?
A: Yes. Konmask offers exchange programs where you ship your failed unit and receive a tested replacement, reducing your net cost. Repair evaluation is also available for select boards. Contact us for details.
Q: What is the lead time for DS200TCERG2BTF?
A: Lead time depends on current stock status. In-stock units typically ship within 2–3 business days of payment confirmation. For out-of-stock units, sourcing lead time is typically 1–3 weeks. Submit an inquiry for real-time availability.
Q: Is a warranty provided?
A: Yes. Konmask provides a limited warranty on all tested and refurbished units. Warranty terms are specified in the quotation. New surplus units carry OEM warranty terms where applicable.
