Overview
AS-Interface extension plugs compact
With the extension plug it is possible to double the cable length
possible in an AS-Interface segment from 100 to 200 m.
Only one power supply unit is needed to supply power to the
slaves on the up to 200 m long segment.
The extension plug compact can be installed directly onto an
AS-i shaped cable. A separate M12 feeder, as was required for
earlier extension plug versions, is no longer required with exten-
sion plug compact.
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 is installed in a radius of around ± 10 m at the point of the
network that is furthest from the power supply unit. The extension
plug is not allowed to be used in AS-Interface networks smaller
than 100
m. As with all AS-Interface networks, any network struc-
ture (line, tree, star) is possible when using the extension plug.
Only one extension plug is required per 200 m segment even
with a tree or star structure.
Note:
The AS-i bus cable must not terminate in the extension plug
compact. The AS-Interface shaped cable can be terminated by
means of a cable terminating piece to provide degree of protec-
tion IP67 where required,
see "Other accessories" on page 2/99
.
The AS-Interface extension plug is not suitable for
AS-i Power24V networks.
