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 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.
