■ Overview
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 / extension plug plus is a passive component
which is connected to that point of the AS-Interface network that
is furthest away from the power supply. It has an M12 connector
for quick connection 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.
The extension plug / extension plug plus has integrated under-
voltage detection for monitoring the AS-Interface voltage in or-
der to be sure that the necessary voltage still exists at the end of
the bus cable. Undervoltage is signaled on the extension plug
by means of a diagnostics LED. The extension plug plus is
equipped with an AS-Interface slave and communicates this
diagnostics information directly to the AS-Interface master.
■ Benefits
• Doubling of the cable length from 100 to 200 m per
AS-Interface segment
• More possibilities of use and greater freedom for plant plan-
ning through doubling of the AS-Interface segment
• Notable reduction of network infrastructure costs for large
networks
• Enables in combination with repeaters a maximum range of up
to 600 m for AS-Interface networks (for details see section
Configuration in the LV1 T "Technical Information")
• Easy monitoring through integrated undervoltage detection
■ Selection and ordering data
1)
For connection to the AS-Interface flat cable you need the AS-Interface
M12 feeder, which must be ordered separately (see section Accessories).
