Allen-Bradley 1756-EN2T Ethernet IP Network Interface Module

The Allen-Bradley 1756-EN2T Ethernet/IP Network Interface Module is a two-port EtherNet/IP communication module for Rockwell ControlLogix systems that connects a 1756 backplane to a 10/100 Mbps Ethernet network. It provides two RJ-45 ports for EtherNet/IP data transfer and supports up to 128 TCP connections, enabling multiple simultaneous client and server communications between the controller, HMIs, SCADA systems, and other Ethernet devices. Designed as part of the 1756 Ethernet/IP bridge family, the EN2T delivers direct access to I/O data over standard Ethernet, eliminating the need for a separate gateway in many deployments and offering a continuous isolation rated up to 30 V. Common applications include linking a ControlLogix CPU with HMIs and SCADA systems, remote I/O networks, and data collection architectures on industrial Ethernet, with related EN2T variants such as EN2TR and EN2TXT available for different installation needs.
