All the units used within a safety function must be considered when calculating the safety
characteristic data.
INFORMATION
A safety function's SIL/PL values are
not
identical to the SIL/PL values of
the units that are used and may be different. We recommend that you use
the PAScal software tool to calculate the safety function's SIL/PL values.
Supplementary data
CAUTION!
It is essential to consider the relay's service life graphs. The relay outputs'
safety-related characteristic data is only valid if the values in the service life
graphs are met.
The PFH value depends on the switch frequency and the load of the relay output.
If the service life graphs are not accessible, the stated PFH value can be used irrespective
of the switch frequency and the load, as the PFH value already considers the relay's B10d
value as well as the failure rates of the other components.
