MARK-II Control Systems for GE Gas Turbines

Contacting General Electric is your best bet. This is an old obsolete GT control system.

Thanks for replay,

I Know that this is a oldest system for turbine control. But the suppier maintenain it at a Black box they dont give the detail about the system hence I want to know about the system.

I think you are going to be out of luck getting much assistance. Prior to the Mark 4 the system was mostly referred to as "Speedtronics". The relaying and such used industry standard designators and should be recognizable (maybe not easily) by name.

It was a standard analog system with relay logic. I wish you luck.

My experience with GE turbine controllers is that they are their business and you don't get a chance to mess with them. Good luck and let us know if you find any information.
