■
Overview
• Repeater for extending the AS-Interface cable by 100 m in
each case
• Extender for increasing the distance (max. 100 m) between
the master and the AS-Interface segment
• Up to two repeaters, or one extender and one repeater can be
used in series
• A parallel connection of several repeaters is possible (star
configuration)
• Maximum extension of an AS-Interface network can thus be in-
creased to 500 m
• Simple assembly technology
• IP67 module housing
■
Benefits
Repeaters
• Expansion of the range of applications and greater freedom in
plant design by extending the AS-Interface segment
• Reduction of standstill or service times in the event of a fault
with separate display of the correct AS-Interface voltage for
each end
Extenders
• Expansion of the range of applications and greater freedom in
plant design by extending the AS-Interface segment
• When the extender is used, the master can be located at a dis-
tance of up to 100 m and a power supply is not required at the
master end.
■
Application
The repeater is used in order to extend the AS-Interface seg-
ment by 100 m, whereby AS-Interface slaves and one AS-Inter-
face voltage supply are located on each side of the repeater.
The extender is used to increase the distance between the
master and the AS-Interface segment with the AS-Interface
slaves to a maximum of 100 m. On the side of the master there
are no AS-Interface slaves and no AS-Interface voltage supply.
