Beckhoff Automation EK1100 EtherCAT Coupler Module

Beckhoff EK1100 EtherCAT Coupler Module, Rev 0018, is the standard interface that bridges an EtherCAT master to Beckhoff EtherCAT Terminals (ELxxxx/ESxxxx/EMxxxx), enabling scalable I/O expansion within a control cabinet or machine enclosure. As a dedicated EtherCAT bus coupler, the EK1100 translates between the EtherCAT Device Protocol on the master and the Beckhoff terminal blocks on the field side, forming the essential link that carries the EtherCAT communications and I/O data across the network. This revision in the EK1100 family is designed to be mounted with Beckhoff EL/EM/ES I/O modules and is used to connect them to the EtherCAT bus for synchronous, real-time I/O operations across the automation system. Typical applications include panel-mounted automation, packaging lines, and machine control where a compact, modular bridge to a broad range of digital, analog, and safety I/O modules is needed to build a scalable EtherCAT network.
