Allen-Bradley 1734-AENTR Communication Adapter Module

Allen-Bradley 1734-AENTR Communication Adapter Module is a two-port EtherNet/IP POINT I/O adapter (Catalog Number 1734-AENTR) that serves as the network interface between a POINT I/O rack and a Rockwell Automation controller. It provides two Ethernet/IP ports configured as an embedded switch, enabling flexible topologies such as star, tree, linear, and ring within a POINT I/O network. As part of the POINT I/O family, this dual-port adapter plugs into a POINT I/O chassis and uses EtherNet/IP to exchange I/O data with the controller, supporting standard POINT I/O communication protocols and enabling scalable, distributed I/O connectivity in Industrial Ethernet architectures.
