JUMO dTRANS T06 - Calculations of the DIN en ISO 13849-1 Performance Level - 707071;X - 23;XXX (AC240 V); Calculations of the DIN en ISO 13849-1 Performance Level - 707071;X - 29;XXX (DC24 V)

The following table shows the achievable PL level for the two voltage versions:
6.7.2 Calculations of the DIN EN ISO 13849-1 performance level – 707071/X - 23/XXX (AC240V)
6.7.3 Calculations of the DIN EN ISO 13849-1 performance level – 707071/X - 29/XXX (DC24V)
The two variants of the dTRANS T06 meet the architecture requirements for a category 2 system. The necessary limit values
according to DIN EN ISO 13849-1, Table K.1 for performance level c and the fundamental and established safety principals
are adhered to for all voltage versions of type 707071 considered.
If the temperature transmitter is used redundantly (i.e. HFT = 1), the requirements for a category 3 system are adhered to. The
necessary limit values according to DIN EN ISO 13849-1, Table K.1 for performance level d are met here for both voltage ver-
sions.

-value Reference value for a preventative replacement (10 % of the B10d value). At this
value, a dangerous failure has already occurred for approx. 63 % of all compo-
nents.
In this case, the standard DIN EN ISO 13849-1 recommends replacement.
