Connector board AF
Description and ordering data
Fig. 4/11 Connector board AF ”Remote bus” 6DS9 203--8DA, with
mounting plate
Application
To convert the remote bus coaxial cable to the two lengths of
coaxial cable fixed in the bus converter UI and to convert the
standard remote bus cable and the remote bus cable for special
applications to thin remote bus cable (Inhouse cable). To termi-
nate the remote bus coaxial cable with the characteristic imped-
ance. For uninterruptable switching on and off of remote bus
participants.
The connector board AF with mounting plate is provided for the
AS 235 and AS 235 H automation systems which are installed in
standard cabinets, the OS 265-3 operation and monitoring sys-
tem (rack version), the bus coupler and the SIMATIC S5-155U
programmable controller.
The connector board AF without mounting plate is provided for
the AS 235 K automation system and for the remote bus con-
nection unit (page 4/11).
For applications in critical environments (EMC), the connector
board AF can be retrofitted with an overvoltage fine protection
device.
Possible locations:
AS 235, AS 235 H, OS 265-3 systems and SIMATIC S5: On
the front right-hand cabinet member, up to 2 connector
boards can be mounted on 1 cabinet member
AS 235 K system: In the subrack on the left of the power sup-
ply assembly
Remote bus connection unit: In the subrack.
