The instrument is suitable for use in single-channel safety-related systems in ac-
cordance with IEC 61508 and IEC 61511 up to SIL 2. In a redundant configuration
(HFT ≥ 1), the instruments can be used in a redundant design up to SIL 3.
The instrument is suitable for use in single-channel safety-related systems in ac-
cordance with ISO 13849 up to PL d. In a redundant configuration (HFT ≥ 1), the
instrument can be used up to PL e, if a sufficient external diagnosis is implemen-
ted (DC low for PL d / medium for PL e).
