Technische Daten_Satz No.
No. stands for order number.
Si-Kennzahlen_alle
Si-Kennzahlen_Zusatz_Relais_1kan_EN954_Cat2
Requirement on 1-channel relay outputs for Cat. 2 in accordance with
EN 954-1: An additional output switches to a safe condition in the event
of an error or, if that is impossible, signals a hazardous condition.
Si-Kennzahlen_Zusatz_Relais_Lebensdauer_BA
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.
Si_Kennzahlen_Erläuterung
All the units used within a safety function must be considered when cal-
culating the safety characteristic data.
Technische Daten_Satz Normen
The standards current on 2009-01 apply.

CAUTION!
It is essential to consider the relay's service life graphs. The relay
outputs' safety-related characteristic data is only valid if the val-
ues in the service life graphs are met.
