Allen‑Bradley 1769‑AENTR CompactLogix EtherNet/IP Adapter 2 Port 10/100 Mbps DLR

Dual‑port EtherNet/IP communication module for CompactLogix systems, enabling distributed I/O over Ethernet networks with support for linear, star, and Device Level Ring (DLR) topologies.

The Allen‑Bradley 1769‑AENTR is a single‑slot EtherNet/IP adapter designed to connect 1769 Compact I/O modules to a Logix controller over an EtherNet/IP network. It features two built‑in 10/100 Mbps Ethernet ports with embedded switch technology, supports up to 128 logical communications and 96 TCP/IP connections, and allows users to reuse existing 1769 I/O when migrating to next‑generation CompactLogix controllers. Used in CompactLogix 1769 automation systems with PLC, I/O, HMI, and industrial network components.
