in a control cabinet with a protec­tion type of at least IP54.

 Use the notch on the rear of the unit

to attach it to a DIN rail.

 Ensure the unit is mounted securely

on a vertical DIN rail (35 mm) by us­ing a fixing element (e.g. retaining
bracket or an end angle).

Service life graph

Lebensdauerkurve_Rela is_Text vor Kurv e

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.

Lebensdauerkurve_Rela is_Text nach Kurv e_SIS212_SIR-SLR B sp

Example

 Inductive load: 0.2 A
 Utilisation category: AC15
 Contact service life: 1 000 000 cy-

cles
Provided the application requires few­er than 1 000 000 cycles, the PFH

value (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

Lebensdauerkurve

freewheel diodes for spark suppres­sion.

We recommend you use semiconduc­tor outputs to switch 24 VDC loads.

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 11/03 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

350 g No. 774500, 774502, 774508

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.
