Unit description
Bestimmung/Gertebesch reibung Kontakter weiterungen Schalt _PNOZ
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 all
safety relays with feedback loop monitoring.
The category that can be achieved in
accordance with EN 954-1 and
EN ISO 13849-1 depends on the cate-
gory 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 safety functions on the existing circuit
are transferred to the contact expansion module.
The safety function remains effec-
tive in the case of a component failure.
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.

Please note:
Information given in the “Technical
details” must be followed.
Outputs 13-14, 23-24, 33-34, 43-
44, 63-64, 73-74, 83-84, 93-94 are
safety contacts, output 51-52 is an
auxiliary contact (e.g. for display).
To prevent contact welding, a fuse
should be connected before the
output contacts (see technical details).
Calculation of the max. cable runs
in the input circuit:

Use copper wire that can withstand
60/75 °C.
Sufficient fuse protection must be
provided on all output contacts with
capacitive and inductive loads.
