Unit description
Bestimmung/Gertebeschreibung Kontakterweiterungen 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.
Safety features
Sicherheitseigenschaften Kontakterweiterungen allg_PNOZ The unit meets the following safety requirements:
The contact expansion module expands
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 effective
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.
