Unit description
][Gertebeschreibung PZE Schalt_Steu_OSSD
The unit meets the requirements of
EN 60204-1 and IEC 60204-1. The
contact expansion module is used to
increase the number of contacts available on a base unit. Base units are all
` Safety relays with feedback loop
` Programmable safety systems with
feedback loop
` Units with OSSD semiconductor
outputs and feedback loop
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 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
are safety contacts.
` To prevent contact welding, a fuse
should be connected before the
output contacts (see technical details).
