The 1834-AENTR module acts as the central EtherNet/IP communication hub for Rockwell Automation's In-Cabinet Distributed I/O system. Designed to reduce wiring complexity and panel space requirements, this adapter supports up to 39 downstream nodes through flat media cabling and integrates directly with Logix-based controllers. It features dual RJ45 ports for star, linear, or ring topologies and offers built-in dual power switching, enabling device-level power isolation. Diagnostic LEDs and Studio 5000 support provide comprehensive system visibility and simplified commissioning. This gateway is ideal for high-density, panel-based I/O systems requiring rapid deployment and minimized downtime.
