SolutionsThe Mitsubishi Electric Total Advanced Control (MELTAC®) Digital I&C Platform is built around a common controller for both safety and non-safety related plant control functions.
MELTAC® is currently installed in over 450 applications at over 24 operating nuclear power plants and has over 30 million hours of operating experience with zero plant trips due to software or hardware failures.
The latest generation of the MELTAC® Digital I&C Platform, MELTAC-N, has been utilized in non-safety applications since 2001 and for safety critical control applications since 2009.
