Unit description
Gertebeschreibung
The unit meets the requirements of
EN 60947-5-1, EN 60204-1 and
VDE0113-1. In conjunction with a base
unit the unit is used as a
` Contact expansion module to increase
the number of contacts
available on a base unit. Base units
are all safety relays with feedback
loop monitoring.
` Pulse relay
– In accordance with
EN ISO 12100-1 and
EN ISO 12100-2 (inching circuit
for limited movement of hazardous
machine components during
installation, set up and positioning)
– in safety circuits in accordance
with VDE 0113 and EN 60204-1
(e.g. on movable guards)
` Safe timer relays
– in accordance with EN 1088 (release
with delay through timer)
– in safety circuits in accordance
with VDE 0113-1 and EN 60204-
1 (e.g. on movable guards)
