Allen-Bradley 1734-AENTR EtherNet/IP Interface Module

The Allen-Bradley 1734-AENTR EtherNet/IP Interface Module is a two-port POINT I/O Ethernet adapter that serves as the EtherNet/IP interface between a Rockwell Automation controller and POINT I/O modules. It provides dual RJ-45 Ethernet ports for network connectivity and daisy-chaining, enabling a distributed I/O topology over standard Ethernet networks. The adapter is designed for POINT I/O and forms part of the POINT I/O family, connecting to your controller over EtherNet/IP while power and signaling to attached POINT I/O modules run from a field-side 24V DC supply. The unit accepts 24V DC field power up to 28.8V, rated at up to 400 mA, and supports fieldbus power up to 10 A. This configuration makes it suitable for remote I/O across manufacturing lines, packaging, or material handling systems where reliable, scalable I/O is required. Typical applications include distributing digital input, digital output, or specialty POINT I/O modules across an Ethernet-based control system, with the two-port arrangement allowing network topology flexibility. The 1734-AENTR is a Rockwell Automation product used with compatible POINT I/O racks and controllers to enable fast, deterministic I/O communication over EtherNet/IP.
