Application
Toconver t signals from a 20-m local bus t o a 4-km remote bus.
Signal coupling-in and coupling-out induct ive and without feed-
back.
Design
The bus converter consist s of 3 single-height modules.
Front panel width:
Power supply unit 30.48 mm = 2 standard slots
Bus interface 15.24 mm = 1 s tandard slot
Inductive coupler 45.72 mm = 3 standard slots
The bus interface module has a 20-m l ocal bus interface and
constitutes the input of t he bus converter. The inductive coupler
module has 2 lengths of coaxial cable f ixed 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 :
AS235 K automation system,basic unit
AS 235automation system, powerdistribution subrack in the
basic cabinet
AS 235H automation system, powerdistribution 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. f or SIMATIC S5-155 U,
SICOMP industry-st andard PC or OS 265-3 rack-type version)
Bus coupler (BK-FF).
