Unit description
Gertebeschreibung
The unit meets the requirements of
EN 60947-5-1, EN 60204-1 and
VDE 0113-1. The contact expansion
module is used to increase the number
of instantaneous safety contacts available on a base unit. Base units are

The category that can be achieved in
accordance with EN 954-1 and
EN ISO 13849-1 depends on the category of the base unit. The contact expansion module may not exceed this.
Safety features
Sicherheitseigenschaften Kontakterweiterungen allg_PNOZ
The unit meets the following safety requirements:
The contact expansion module ex-
pands an existing circuit. As the
output relays are monitored via the
base unit's feedback loop, the safe-
ty functions on the existing circuit
are transferred to the contact ex-
pansion module.
The safety function remains effec-
tive in the case of a component fail-
ure.
Earth fault in the feedback loop:
Detected, depending on the base
unit that is used.
Earth fault in the input circuit:
The output relays de-energise and
the safety contacts open.

Outputs 13 -14, 23 -24, 33 - 34 are
safety contacts; outputs 41 - 42 are
auxiliary contacts (e.g. for display).
To prevent contact welding, a fuse
should be connected before the
output contacts (see technical details).
AC DC
3 safety contacts and 1 auxiliary
contact each; these can be control-
led separately
Use copper wire that can withstand
60/75 °C.
Sufficient fuse protection must be
provided on all output contacts with
capacitive and inductive loads.

Connect the contact expansion
block using the connector supplied.
Control cabinet installation
The safety relay should be installed
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).
Push the unit upwards or downwards
before lifting it from the DIN rail.

Service life graph
Lebensdauerkurve_R elais_Text vor Kur ve
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: 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
freewheel diodes for spark suppression.

safety-related characteristic data is
only valid if the values in the service life
graphs are met.
The PFH value depends on the switching frequency and the load on the relay

NOTICE
The safety-related characteristic data
applies per channel of the contact expansion block. The safety-related
characteristic data of the base unit and
all other devices that are used must be
taken into account when calculating
the safety function. We recommend
that you use the PAScal software tool
to calculate the safety function's SIL/
PL values.
