Frequently Asked Questions

What is the GE Speedtronic Mark VI system?
Mark VI is GE's turbine control platform for gas and steam turbines, providing control, protection and monitoring with simplex or triple-redundant (TMR) architecture. It succeeded the Mark V platform.
Are Mark V spare boards still needed today?
Yes, many power plants still run Mark V control systems, and replacement boards are needed to keep turbines available. Tested spares avoid costly unplanned outages.
What does TMR mean in a GE turbine control system?
Triple Modular Redundancy uses three independent controllers voting on each output. A single board failure does not trip the turbine, improving availability.
Can a Mark V system be upgraded to Mark VI or Mark VIe?
Yes, GE offers migration paths that reuse field wiring while replacing controllers and I/O. Upgrades improve diagnostics, cybersecurity and parts availability.
How are GE control boards tested before supply?
Boards should be function-tested on a test bench or simulator and checked for correct revision level. Matching the exact part number and revision is essential for compatibility.
