Beckhoff BK1150 | EtherCAT Compact Bus Coupler

The BK1150 EtherCAT Coupler is the link between the EtherCAT protocol at fieldbus level and the Bus Terminals. The coupler

converts the passing telegrams from Ethernet 100BASE-TX to the internal, fieldbus-independent terminal bus. A station consists of

a coupler and up to 64 Bus Terminals plus a bus end terminal. The process image of the EtherCAT system is assigned automatically.

Up to 255 Bus Terminals can be connected via the K-Bus extension.

Special features:

• Compact design

• Connection technology: 2 x RJ45 socket

• Connection lengths: up to 100 m

• connects the EtherCAT protocol with the Bus Terminals

The BK1150 works in the same way as the BK1120 and complements this series with its compact design. The coupler has two RJ45

sockets. The upper Ethernet interface is used to connect the coupler to the network; the lower socket serves for the optional

connection of further EtherCAT devices in the same segment. The system and field supply, each 24 V DC, is provided directly at the

coupler. The attached Bus Terminals are supplied with the current required for communication from the supplied system voltage.

The field supply is forwarded to the individual I/O components via the power contacts with up to 10 A. The Bus Terminals are

parameterized via ADS through the KS2000 software; a KS2000 connector is not required. Alternatively, the controller (PLC, IPC) can

configure the Bus Terminals via PLC function blocks.

In the EtherCAT network, the BK1150 coupler can be installed anywhere in the Ethernet signal transfer section (100BASE-TX)

except directly at the switch. The EK9000 and EK1000 couplers are suitable for use at the switch.
