The service life graphs indicate the
number of cycles from which failures
due to wear must be expected. The
wear is mainly caused by the electrical
load; the mechanical load is negligible.

Si-Kennzahlen_Zusatz_Relais_Lebensdauer_PDB
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.
All the units used within a safety function must be considered when calculating the safety characteristic data.
Technische Daten_Satz No rmen
The standards current on 2009-11 apply.
][Dauerstrom_DC
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.
