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.

Installation

Montage_PNOZ_X

` 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).
