Turbine Overspeed Protection Solution – GE DS200TCEAG1BSF | Mark VI Series
Where This Product Is Used
The GE DS200TCEAG1BSF Emergency Overspeed Board is a critical safety and control component deployed in GE Mark VI Turbine Control Systems. It is engineered for continuous operation in high-stakes industrial environments where turbine runaway events must be detected and arrested within milliseconds. Typical deployment sites include:
- Gas turbine power generation plants (combined-cycle and simple-cycle)
- Steam turbine installations in petrochemical and refinery facilities
- Offshore oil & gas platforms requiring SIL-rated overspeed protection
- Industrial co-generation systems with Mark VI-based DCS integration
- LNG liquefaction train turbine drivers

Application-Specific FAQ
Q: Is the DS200TCEAG1BSF compatible with both Mark VI and Mark VIe systems?
A: The DS200TCEAG1BSF is designed for the Mark VI platform. Mark VIe uses a different I/O architecture; please contact us to confirm compatibility with your specific controller revision.
Q: Can this board be repaired, or must it be replaced?
A: GE recommends board-level replacement for safety-critical overspeed boards. Konmask.com supplies tested replacement units to minimize downtime.
Q: What is the typical failure mode that requires replacement?
A: Common failure indicators include nuisance trips, failure to trip on test, IONet communication faults, and diagnostic alarms L3DIAG_TCEG on the HMI.
Q: Do you provide a warranty?
A: Yes. All units carry a 12-month warranty against defects in materials and workmanship under normal operating conditions.
Q: Can you supply the full Mark VI control panel or just individual boards?
A: Both. Konmask.com supplies individual boards, complete panel assemblies, and turnkey Mark VI system upgrades. Contact us for project-specific requirements.
