The GE Mark V Speedtronic remains one of the most widely deployed turbine control platforms in the power generation and industrial sectors. Introduced in the late 1980s, it brought Triple Modular Redundancy (TMR) architecture to gas and steam turbine management — a design so reliable that thousands of plants worldwide continue operating it today, decades after OEM production ended. https://evaflux.com/product-category/ge-speedtronic-ge-excitation/ge-mark-v/
