Service life graph
Lebensdauerkurve_Relais_Text vor Kurve
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.

Example
?Inductive load: 0,2 A
?Utilisation category: AC15
?Contact service life: 2,000,000 cy-cles
Provided the application requires few-er than 2,000,000 cycles, the PFH val-ue (see technical details) can be used in the calculation.
To increase the service life, sufficient spark suppression must be provided on all output contacts. With capacitive loads, any power surges that occur must be noted. With contactors, use freewheel diodes for spark suppres-sion.

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.
The PFH value depends on the switch-ing frequency and the load on the relay output.
If the service life graphs are not acces-sible, the stated PFH value can be used irrespective of the switching fre-quency and the load, as the PFH value already considers the relay's B10d val-ue as well as the failure rates of the other components.

All the units used within a safety function must be considered when calculating the safety characteristic data.
