Allen-Bradley 1734-AENT Point I/O Adapter Module

The Allen-Bradley 1734-AENT Point I/O EtherNet/IP adapter module is a single-port Ethernet I/O adapter that serves as the gateway between a POINT I/O rack and an EtherNet/IP network. As part of the POINT I/O family, it provides the Ethernet/IP communication path from the POINT I/O backplane to the controller, typically through a local 1756-ENBT module, and supports the range of 1734 I/O modules mounted in the same rack. The adapter is a 1-port Twisted Pair media adapter with a standard RJ45 Ethernet connection and is powered from a 24V DC supply to link the POINT I/O rack’s I/O modules to the EtherNet/IP network. Cataloged as 1734-AENT, it is widely used to enable distributed I/O expansion within Rockwell Automation control architectures by connecting POINT I/O racks to the EtherNet/IP network. Rockwell’s Point I/O documentation positions the 1734-AENT as the Ethernet/IP bridge for POINT I/O systems, a role reinforced in the 1734-UM011D-EN-P user manual, which describes the adapter as the child to a local 1756-ENBT and integral to the POINT I/O architecture.
