Allen-Bradley 1734-AENT EtherNet/IP IO Adapter

The Allen-Bradley 1734-AENT is a single-port EtherNet/IP POINT I/O adapter that bridges a POINT I/O rack to an Ethernet/IP network. Designed as a Twisted Pair media adapter, it operates on 24V DC and is DIN-rail mountable as part of the POINT I/O family. It provides one RJ45 Ethernet port for network communications to a Rockwell Automation controller, enabling I/O data exchange over EtherNet/IP and supporting both I/O messaging and explicit messages. IP configuration supports DHCP, BOOTP, or a static address set with the adapter's thumbwheel switches or retrieved from nonvolatile memory, giving deployment flexibility across networks. The mounting and installation considerations, including DIN-rail positioning, are described for POINT I/O EtherNet/IP adapters. It connects to a Rockwell Automation control system via EtherNet/IP for distributed I/O with POINT I/O modules. The standard 1734-AENT is the baseline single-port model, with variants such as 1734-AENTR (dual-port) and 1734-AENTK (conformal-coated) available for different environments.
