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 category of the base unit. The contact expansion module may not exceed this.
][Gertebeschreibung PZE Kat. 3
The delay-on de-energisation safety
contacts may only be used up to category 3.
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 17-18, 27-28, 37-38, 47-48
are delay-on de-energisation safety
contacts.
` To prevent contact welding, a fuse
should be connected before the
output contacts (see technical details).

` Use copper wire that can withstand
60/75 °C.
` Sufficient fuse protection must be
provided on all output contacts with
capacitive and inductive loads.
` Single-channel operation: one in-
put circuit affects both output relays
