EtherCAT plug-in modules

With the EtherCAT plug-in modules from the EJ series, Beckhoff, a specialist for PC- and EtherCAT-based automation solutions, provides the possibility of making serial productions with medium and high quantities much more efficiently. The EJxxxx EtherCAT plug-in modules are electronically based on the well-known EtherCAT I/O system and their design allows them to be directly plugged to a circuit board. The circuit board is an application-specific signal distribution board that distributes signals and power supply to individual plug connectors in order to connect the controller to further machine modules. Elaborate manual wiring of single wires, common in conventional control cabinet construction, is replaced by simply plugging in prefabricated cable harnesses. Unit costs are lowered and the risk of incorrect wiring is reduced to a minimum by coded components.

application parameters

The EtherCAT plug-in modules are not only electronically based on the well-known EtherCAT Terminals but also provide their wide range of signals, including functional safety (TwinSAFE). The electromechanical design enables the modules to be plugged directly into an application-specific signal distribution board with outsourced wiring level. This circuit board distributes signals and power supply to individual application-specific plug connectors in order to connect the controller to further machine modules. The combination of I/O modules, signal distribution board and pre-assembled cables implements the plug & work idea consistently.
