The open I/O system from Beckhoff with protection class IP 67 supports twelve different fieldbus systems, including four Industrial Ethernet variants: Ethernet TCP/IP, EtherCAT, PROFINET, and now also EtherNet/IP.With the extension of the Fieldbus Box family through the IL230x-B905 modules, EtherNet/IP users can now benefit from comprehensive IP 67 functionality. The robust fieldbus modules are equipped with Ø8, M8 or M12 signal connections.A standardized d-coded M12 socket is used for the connection between EtherNet/IP and the Fieldbus Box, forming a secure connection system. Confusion of the connectors or cables with sensor or other fieldbus connections is avoided through coding. Up to 120 Extension Box modules can be connected via the integrated IP-Link connection.
