All the units used within a safety function must be considered when calculating the safety
characteristic data.
The PFH value depends on the switching frequency and the load on the relay output.
If the service life graphs are not accessible, the stated PFH value can be used irrespective
of the switching 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.
