GE Energy
Measurement & Control Solutions
You can now elegantly modernize your legacy Mark V control system
to GE’s most advanced control platform, the Mark VIe, through a
simple plug-and-play exchange of the electronic modules. With
no change to site wiring, panel terminations, turbine field devices,
or panel size, the migration significantly expands your system’s
capabilities while completely addressing all obsolescence issues. The
solution ensures continued OEM support and the ability to grow and
do more with your control system. It is designed to replace all Mark
V control systems, except for those on LM (aeroderivative) turbines.
