Intended use
The unit meets the requirements of EN 60947­5­1, EN 60204­1 and VDE 0113­1. The con­
tact 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 ISO 13849­1 depends on the
category of the base unit. The contact expansion module may not exceed this.
The delay­on de­energisation safety contacts may only be used up to max. PL d (Cat. 3).
