Product Introduction
The Allen-Bradley 1738-AENT EtherNet/IP Adapter is a dedicated ArmorPoint I/O communication adapter designed to enable high-performance Ethernet-based connectivity between distributed field-level I/O devices and Rockwell Automation control systems. As a core component of the ArmorPoint I/O platform, it allows decentralized I/O stations to communicate efficiently over EtherNet/IP networks.
The adapter is engineered for direct installation at the machine level, supporting harsh industrial environments where traditional control cabinet mounting is impractical. Its robust mechanical design and high ingress protection ratings ensure reliable operation in applications exposed to dust, moisture, vibration, and wash-down conditions.
By serving as an EtherNet/IP network interface, the 1738-AENT enables deterministic cyclic data exchange between field devices and controllers. This architecture improves system responsiveness, simplifies wiring structures, and enhances overall diagnostic capability, making it suitable for modern distributed automation systems.
