2 Product Overview
2.1 Functional description
System expansion
Based on a bus terminal block consisting of a Bus Coupler and a maximum of 64 Bus Terminals, using the
K-bus Extension Terminals KL9020 and KL9050 your system can be expanded by up to 31 terminal blocks.
The expansion terminal blocks can be equipped with a maximum of 64 Bus Terminals each. The maximum
permissible configuration consists of 255 Bus Terminals and 1020 I/Os. The K-bus Extension Terminals
KL9020 and KL9050 enable a distance of 5 m max. between two terminal blocks and therefore an overall
system length of 155 m.

The K-bus Extension Terminals KL9020 and KL9050 integrate seamlessly into the Beckhoff Bus Terminal
system in terms of their appearance and functionality. The transparent terminal lugs used for labelling
indicate their function as system terminals.
KL9020
The End Terminal with RJ45 socket ( KL9020 [
}
11] ) is plugged into the end of the bus terminal block
instead of a standard End Terminal (KL9010) and enables the connection of the K-bus extension cable. The
electronics of the KL9020 are supplied via the K-bus from the Fieldbus Coupler.
KL9050
In the expansion terminal blocks, the Coupler Terminal KL9050 [ } 12] replaces the Fieldbus Coupler and
takes over its function. It is mounted on the mounting rail [ } 17] at the start of the extension station and
connected to the preceding Bus Terminal block via an RJ45 socket with the designation IN by means of a K-
bus extension cable with a maximum length of 5 m. Connect the K-bus extension cable
• of the first expansion terminal block to the End Terminal with RJ45 socket (KL9020) of the terminal
block with the Fieldbus Coupler.
