■ Overview
AS-Interface extension plug (on AS-Interface M12 feeder)
With the extension plug/extension plug plus it is possible to
double the cable length possible in an AS-Interface segment
from 100 to 200 m.
The extension plug is a passive component, the extension plug
plus is equipped in addition with an A/B slave.
The extension plug / extension plug plus has an M12 plug and
can be connected with it to the AS-Interface M12 feeder with
degree of protection IP67. Only one power supply unit is needed
to supply power to the slaves on the up to 200 m long segment.
Design of an AS-Interface segment with an extension plug
To construct an AS-Interface segment with a cable length of
more than 100 m and up to a maximum of 200 m, the extension
plug or extension plug plus is installed at that point of the net-
work which in a range of approx. ±10 m is furthest from the
AS-Interface power supply unit. The extension plug is not al-
lowed to be used in AS-Interface networks smaller than 100 m.
As with all AS-Interface networks, any network structure (line,
tree, star) is possible when using the extension plug/extension
plug plus. Only one extension plug/extension plug plus is
required per 200 m segment even with a tree or star structure.
Note:
The AS-Interface extension plug and the extension plug plus are
not suitable for AS-i Power24V networks. Both are recom-
mended for use in AS-Interface networks with AS-Interface
power supply units (e.g. 3RX9 501-0BA00).
Maximum network size with repeaters and extension plug (master at center of network)
