Overview
The Allen-Bradley 1734-AENT is a POINT I/O Ethernet network adapter that enables seamless EtherNet/IP communication within distributed I/O systems. As a sealed, DIN-rail mounted module, the 1734-AENT integrates Ethernet connectivity into POINT I/O racks, allowing controllers to communicate with remote I/O modules over industrial Ethernet networks. This adapter is essential for modern production environments requiring deterministic real-time data exchange across facility networks.
Key Features
- EtherNet/IP communication protocol support for Standards-based connectivity
- 10/100 Mbps Ethernet speed with half or full-duplex operation modes
- Sealed, open-style enclosure designed for industrial cabinet and harsh field environments
- DIN-rail mounting for compact installation alongside other POINT I/O modules
- 24 Volt DC nominal supply with flexible operating range (10–28.8V DC)
- Low power consumption (4.5W typical at nominal voltage) reduces energy cost
- Maximum inrush current of 6A for 10ms enables deployment in existing power architectures
