BK1120 BECKHOFF EtherCAT Bus Coupler

• Bus Interface: 2 × RJ45 (built-in daisy-chaining/cascading)
• Data Transfer Rate: 100 Mbit/s (100BASE-TX)
• Power Supply: 24 V DC (-15% / +20%)
• K-Bus Current Supply: 1750 mA
• Power Contacts: Max. 24 V DC / Max. 10 A
• Electrical Isolation: 500 V (contacts / supply / Ethernet)
• Operating Temperature: -25°C to +60°C
• Protection Rating: IP20
• Topology Versatility: The dual RJ45 ports allow the coupler to act as a line or star topology endpoint. The upper port connects to the network segment, while the lower port interfaces with downstream EtherCAT devices.
• Placement Restrictions: In an EtherCAT network, the BK1120 can be positioned anywhere along the 100BASE-TX signal transfer section, except directly connected to a standard Ethernet switch (it requires an EtherCAT Master or an appropriate junction component like an EK1000).
• Configuration: System integration and parameterization can be handled via the Beckhoff KS2000 Configuration Software or through EtherCAT ADS (Automation Device Specification).
• Diagnostics: Features onboard LEDs indicating the status of the EtherCAT state machine (RUN and ERROR), alongside standard indicators for the 24 V coupler supply and active power contact bridging.
