Product Description:
The EK1100 is an EtherCAT bus coupler produced by Beckhoff within the EK EtherCAT Couplers series. It joins an EtherCAT fieldbus segment to the company’s E-bus I/O terminals so distributed signals can be gathered and forwarded to higher-level controllers. In automated cells, the unit acts as the physical and logical bridge that turns terminal-level data into deterministic Ethernet traffic, allowing modular machine sections to be linked without sacrificing cycle time.
The communication side uses a 100 MBaud transfer rate that matches the Ethernet 100BASE-TX standard and lets the device propagate telegrams through its two-port switch. Both network ports are presented as 2 x RJ45 sockets, simplifying daisy-chain wiring. Cabling distances can extend to 100 m between nodes, giving designers freedom in cabinet and machine layout. Telegram processing inside the coupler introduces only 1 µs of typical internal delay, so axis-level synchronization is maintained even in large lines. The coupler identifies itself on the network with the EtherCAT Device Protocol, and automatic addressing recognizes up to 4.2 GB of addressable I/O space without additional configuration steps. Hot-plugging of terminal strings is not available, so segments must be powered down when reconfigured. Electrical operating power for the electronics is supplied at 24 VDC, matching the control voltage found in most panels.
The supply rail is passed forward on power contacts rated for 24 VDC, 10 A, enabling sensors and actuators on the terminals to draw load current directly through the coupler. Downstream modules also receive logic energy through the E-bus, with a maximum backplane output of 5 V, 2 A that supports sizeable terminal stacks before an auxiliary feeder is required. Internal electronics draw 70 mA + (Σ E-bus current / 4), a figure useful when planning cabinet power budgets. The enclosure is classified as IP20, so installation must be inside a shielded cabinet to avoid dust or finger contact.
