As part of the SIL2 design and qualification process, a complete failure mode & effect analysis (FMEA) was performed on the system in order to achieve the highest possible reliability. The resulting design was then validated using stringent environmental testing methods.
R2’s latest generation architecture has been in service since 2007 with thousands of units deployed worldwide in a variety of harsh industrial environments. Millions of hours of operational experience have been accumulated and its analysis shows failure rates to be extremely low, even when compared to what was expected from the calculations.
All units go through strict quality control and are systematically subjected to thermal cycling to ensure the highest quality assembly.
