Allen-Bradley 1769-AENTR EtherNet/IP Network Adapter

The Allen-Bradley 1769-AENTR EtherNet/IP Network Adapter is a dual-port EtherNet/IP communication module that serves as a remote I/O bridge for 1769 CompactLogix I/O. It connects a standalone 1769 backplane to an Ethernet/IP network, enabling distributed I/O to be managed by a Controller over Ethernet. With two RJ-45 10/100 Mbps ports, the 1769-AENTR supports Device Level Ring (DLR) topology and linear network configurations, providing redundancy and flexible wiring for remote I/O drops. The adapter is mountable on a DIN rail or panel, and interoperates within Rockwell Automation’s CompactLogix I/O ecosystem to extend I/O reach beyond the main controller chassis. This device is designed to work with 1769 I/O modules and compatible CompactLogix controllers to facilitate remote I/O, not to add Ethernet to a PLC that lacks Ethernet capabilities. Typical applications include remote sensing, actuation, and data collection in manufacturing environments where CompactLogix controllers monitor or control distributed 1769 modules across an Ethernet/IP network.
