Unit features
Gertemerkmale
Positive-guided relay outputs:
– 6 safety contacts (N/O), instanta-
neous
– 2 auxiliary contacts (N/C), in-
stantaneous
3 safety contacts and 1 auxiliary
contact each; these can be controlled separately
Safety contacts are safely separat-
ed from all other circuits; safety
contacts from Ext.1/O0 are safely
separated from the safety contacts
from Ext.2/O1
Basic insulation between contacts
LED indicator for:
– Input state of channel Ext.1/O0
– Input state of channel Ext.2/O1

spring-loaded terminals or screw
terminals)
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
Speed monitor PNOZ s30
PNOZmulti Mini base units
PNOZ mm0.1p, PNOZ mm0.2p
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.

Wiring
Verdrahtung
Please note:
Information given in the “Technical
details” must be followed.
The wiring guidelines in the base
units' operating instructions must
be taken into account.

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.

Connecting the contact expansion
block to the PNOZ s30 or base unit
PNOZmm0.1p/PNOZ mm0.2p
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.
