Fig. 4/11 Connector board AF ”Remote bus” 6DS9 203-8DA, with mounting plate
Fig. 4/12 Connector board AF ”Remote bus” 6DS9 203-8CA, without 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
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
AS 235 K system: In the subrack on the left of the power sup- ply assembly
Remote bus connection unit: In the subrack.
