Allen-Bradley 1734-AENTR Point I/O Ethernet Adapter

The Allen-Bradley 1734-AENTR Point I/O Ethernet Adapter is an EtherNet/IP adapter module for POINT I/O distributed control systems, delivering dual-port network connectivity to remote I/O assemblies. It provides two RJ45 Ethernet ports with an integrated switch, enabling high-speed communication between field I/O modules and centralized PLC systems. Powered by 24V DC (field power range 10–28.8V DC) with a backplane current draw of 500 mA at 5V DC, this module can support up to 63 POINT I/O modules depending on configuration and is designed for DIN rail mounting in environments ranging from 0°C to 55°C. The adapter operates at 10/100 Mbps and uses EtherNet/IP for real-time data exchange, making it suitable for machine-mounted I/O stations, production lines, packaging equipment, and process control skids where reliable, scalable I/O connectivity is required. Typical applications span material handling, automotive assembly lines, food and beverage processing, water and wastewater facilities, and OEM machinery needing flexible I/O configuration and real-time monitoring. Common replacements include Allen-Bradley 1734-AENT, 1734-EP24DC, and 1794-AENT.
