Allen-Bradley 1769-AENTR Detailed Description
CompactLogix Dual-Port EtherNet/IP Adapter
The Allen-Bradley 1769-AENTR is a CompactLogix EtherNet/IP adapter that bridges a bank of 1769 local I/O modules onto an EtherNet/IP network over standard Cat5e Ethernet cable. As part of Rockwell Automation’s CompactLogix 5370 architecture, this dual-port adapter supports linear, star, and Device Level Ring (DLR) topologies without an external switch, carries up to 128 Logix communication connections and 96 TCP/IP connections, and embeds IP security plus servo technology support for modern machine architectures. Whether you are expanding an existing CompactLogix 5370 L1/L3 system, adding remote I/O to a distributed machine, or replacing a failed 1769-AENTR in a working panel, this adapter delivers deterministic control traffic on a single flat network.
Key Features & Benefits
- Dual-port 10/100 Mbps EtherNet/IP — two RJ45 Category 5 ports with embedded switch logic for daisy-chaining (linear, star, and DLR ring topologies) without external switches.
- High connection capacity — up to 128 Logix communication connections and 96 TCP/IP communication connections for controller and HMI traffic.
- DLR (Device Level Ring) support — fast network fault recovery in ring configurations; ideal for machine builders standardizing on resilient single-network architectures.
- IP security capabilities — built-in IP security helps protect control traffic on the factory network.
- Servo technology support — carries servo drive traffic across the same EtherNet/IP infrastructure.
- 1769 local I/O expansion — adapts up to a bank of 1769 CompactLogix I/O modules (slot width 1) for remote I/O over Ethernet.
- Compact, flexible mounting — DIN rail or panel mount with a slim 50 mm body width; open-style enclosure rated for 0 to 60 °C operation.
Compatible Hardware
The 1769-AENTR works with 1769-series I/O modules, CompactLogix 5370 L1 and L3 controllers (1769-L16ER/L18ER/L19ER/L24ER/L27ER/L30ER/L33ER families), and integrates into Studio 5000 Logix Designer (RSLogix 5000) projects. It shares the same RJ45 Category 5 wiring standard and DLR behavior as the rest of the CompactLogix 5370 family, making it a drop-in fit for existing panels. For applications that need POINT I/O remote adapters instead, see the 1734-AENTR adapter for the 1734 platform.

Why Choose the Allen-Bradley 1769-AENTR
The 1769-AENTR is the standard way to put 1769 local I/O on an EtherNet/IP backbone: it keeps the same dual-port DLR hardware and Category 5 wiring as the CompactLogix 5370 controllers it serves, so machine builders can build flat, resilient single-network architectures without separate infrastructure for remote I/O. Plants standardizing on Rockwell Automation’s Logix platform benefit from common programming tools in Studio 5000, spare-parts interchangeability, and a straightforward expansion path — one adapter brings an entire chassis of 1769 I/O modules onto the network. Every Allen-Bradley 1769-AENTR we ship is tested, backed by warranty, and available both new in original packaging and as a cost-saving refurbished unit.
