The Allen-Bradley 1756-EN2TR EtherNet/IP Interface Module is a dual-port Ethernet interface for ControlLogix controllers, delivering two 10/100 Mbps copper RJ-45 ports for EtherNet/IP communications. It supports up to 128 TCP connections and provides electrical isolation between the Ethernet network and the backplane (30 V continuous), with Ethernet-to-backplane, USB-to-backplane, and USB-to-Ethernet options available on applicable EN2T/EN2TR/EN3TR series. Designed for use in ControlLogix systems, it enables EtherNet/IP messaging and remote I/O communication across a backplane network.
