Allen Bradley 1794-AENTR Adapter Module

The AB 1794-AENTR is a dual-port EtherNet/IP adapter module for the FLEX I/O system, designed to enable distributed I/O control over industrial Ethernet networks. With built-in support for Device Level Ring (DLR) topologies and redundant communication paths, this adapter ensures high availability and reliable connectivity for up to 8 FLEX I/O modules per bank.

Ideal for compact and modular control systems, the 1794-AENTR connects FLEX I/O modules to Logix-based controllers via EtherNet/IP while offering plug-and-play integration, DIN rail mounting, and a 24V DC power supply.
