Allen-Bradley 1769-AENTR | CompactLogix Ethernet Module

Overview

The Allen-Bradley 1769-AENTR is a CompactLogix Ethernet IP adapter that provides dual Ethernet ports for flexible network connectivity. It supports Star, Linear, and Device Level Ring (DLR) topologies for scalable industrial automation.

Electrical and Communication Specifications

This module supports 10/100 Mbps transmission speeds with 128 logical EtherNet/IP connections. TCP/IP connections can reach up to 96 endpoints, while the FlexBus current draw is 500 mA at 5V DC. Users configure the hardware IP address via rotary switches.

Mechanical and Environmental Features

The 1769-AENTR mounts on a DIN rail and occupies one slot in the CompactLogix chassis. Its compact dimensions of 118 x 50 x 87 mm and lightweight 0.280 kg design enable easy installation in tight spaces. The module operates optimally between 0°C and +60°C, while storage tolerates -40°C to +85°C.
