Overview
• Repeaters for extending the AS-Interface cable by 100 m
(max. 300 m possible)
• Repeaters can be cascaded
• Extenders for extending the distance (max. 100 m) between
the master and the AS-Interface segment
• Simple assembly technique
• 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
distance of up to 100 m and a power supply is not required at
the master end.
■
Application
The repeater is used to extend the AS-Interface segment by
100 m.
The extender is used to extend the distance between the master
and the AS-Interface segment with the AS-Interface slaves to a
max. 100 m. A considerably greater cable length than 300 m
can be achieved when the repeaters are connected in parallel.
The maximum extension range is 500 m.
