Allen-Bradley 1756-EN4TR EtherNet/IP Communication Module

The Allen-Bradley 1756-EN4TR EtherNet/IP communication module provides high-speed EtherNet/IP connectivity in ControlLogix systems, with two copper RJ45 ports and two fiber SFP ports to support network redundancy. It supports 10/100/1000 Mbps copper data rates and includes Device Level Ring (DLR) and general network redundancy, mounting in a 1756 ControlLogix chassis slot for installation in industrial automation panels. Common replacements include the Allen-Bradley 1756-EN2TR and 1756-EN3TR, and this module is used across manufacturing lines, process control, oil and gas facilities, power generation, and water treatment environments where robust Ethernet communication for drives, HMIs, remote I/O, and controllers over EtherNet/IP is required.
