Series B FLEX I/O Adapter New | 1794-AENT Allen-Bradley

Allen-Bradley 1794-AENT Series B FLEX I/O EtherNet/IP Communications Adapter

Product Overview

The 1794-AENT (Series B) is a high-performance EtherNet/IP communications adapter designed by Rockwell Automation to interface FLEX I/O modules with industrial Ethernet networks. Serving as a bridge between the field-level Flexbus and a supervisory Logix controller, this adapter facilitates high-speed, deterministic data transfer. The Series B hardware revision is a significant upgrade over previous versions, offering enhanced diagnostic capabilities and improved stability. As an open-style, DIN-rail mounted component, the 1794-AENT is the industry standard for distributed I/O architectures in modern manufacturing and process control environments.

Technical Specifications

The 1794-AENT Series B provides the following technical parameters for system design and integration. Note: While some Series B variants feature dual ports for DLR, the standard 1794-AENT is primarily a single-port RJ45 interface designed for linear and star topologies.
