EtherCAT plug-in modules from the Beckhoff EJ series can be an efficient I/O approach to implement platform concepts in large-scale machine production. These plug-in modules have the performance and functions of the well-known EtherCAT I/O system, while their efficient design enables them to be directly attached to circuit boards.

The circuit board used with the series is an application-specific signal distribution board that transmits signals and power to individual application-specific plug connectors to connect the controller to machine modules as required. Simple, prefabricated, “plug-and-work” cable harnesses replace manual wiring processes.
Unit costs are lowered, and the risk of incorrect wiring is reduced with the coded components in the EJ system.
