Functional safety (SIL)
Functional safety is already activated on instruments with SIL qualification ex factory. On instru-
ments without SIL qualification ex factory, the functional safety must be activated by the user via
the display and adjustment module or via PACTware for applications according to SIL.
Functional safety according to IEC 61508-4
Ʋ Single channel architecture (1oo1D) up to SIL2
2) A suitable cable is the prerequisite for maintaining the protection rating.
