Application
To convert signals from a 20-m local bus to a 4-km remote bus.
Signal coupling-in and coupling-out inductive and without feed-
back.
Design
The bus converter consists of 3 single-height modules.
Front panel width:
Power supply unit 30.48 mm = 2 standard slots
Bus interface 15.24 mm = 1 standard slot
Inductive coupler 45.72 mm = 3 standard slots
The bus interface module has a 20-m local bus interface and
constitutes the input of the bus converter . The inductive coupler
module has 2 lengths of coaxial cable fixed to the front panel.
These are screwed onto the connector board AF (page 4/10)
and form the connection to the remote bus cable.
Possible plug-in locations:
AS 235 K automation system, basic unit
AS 235 automation system, power distribution subrack in the
basic cabinet
AS 235 H automation system, power distribution subrack in
the basic cabinet
Remote bus connection unit (e. g. for OS 520 and OS 265-3
desk-top units)
Remote bus connection subrack (e. g. for SIMATIC S5-155 U,
SICOMP industry-standard PC or OS 265-3 rack-type version)
Bus coupler (BK-FF).

Redundant 24 V supply only when a remote bus connection subrack
6DS4 426--8AA is used
