Allen-Bradley 1734-AENTR Ethernet Interface Module

Allen-Bradley 1734-AENTR is a two-port EtherNet/IP POINT I/O adapter that connects POINT I/O racks to an Ethernet network, serving as the remote interface between distributed I/O modules and the controller. It provides two RJ-45 Ethernet ports for 10/100 Mbps communication and supports Star, Tree, Daisy-chain/Linear, and Ring topologies (DLR capable) for flexible, redundant networking. The module is powered from a field supply of 10–28.8 V DC (typical 24 V), with a maximum power draw around 10.4 W and about 6.3 W of dissipation (≈21.5 BTU/hr). As part of the POINT I/O family, the 1734-AENTR enables Ethernet/IP data exchange between a Rockwell Automation controller and remote I/O modules in industrial environments.
