Allen-Bradley 1734-AENTR POINT IO Ethernet Adapter

The Allen-Bradley 1734-AENTR Ethernet Adapter is a dual-port EtherNet/IP communication module for POINT I/O that provides reliable network connectivity for remote I/O assemblies in POINT I/O distributed control systems. It is commonly installed in machine-mounted I/O stations, production lines, packaging systems, and material-handling equipment, enabling POINT I/O modules to connect to EtherNet/IP networks and to Logix-based automation platforms over Ethernet while supporting Device Level Ring (DLR) topology for network resiliency. Key specifications include two RJ45 ports with auto-negotiating 10/100 Mbps, DIN-rail mounting, a 24 V DC power supply, an operating range of 0 to 55°C (32 to 131°F), and isolation between the communication and field sides. Common replacements include 1734-AENT, 1734-EP24DC, and 1794-AENTR. Typical applications involve connecting POINT I/O modules to EtherNet/IP networks in distributed automation systems such as manufacturing plants, conveyor systems, robotic cells, process skids, and automated assembly machines where remote I/O communication and network redundancy are required.
