FUNCTIONAL SAFETY (DG-TT7-S)
SIL SIL certified based on IEC/EN 61508 part 1 to 7 (2011) standards
Certification delivered by LCIE Bureau Véritas
•
The safety function is either integrating the 4/20 mA current loop, as an output, or the relays
one
•
PFD calculation is based on a 12 months verification frequency and a 24 hours MTTR, out of
the cell
