The Allen-Bradley 1794-AENT is a high-reliability Ethernet/IP adapter module designed for the Flex I/O platform, enabling efficient remote I/O communication over standard 10/100 Mbps Ethernet networks. This module acts as a bridge between the controller (e.g., ControlLogix or CompactLogix) and up to eight Flex I/O modules, supporting both digital and analog signals. With its auto-negotiating Ethernet port, the 1794-AENT ensures seamless integration into existing industrial networks, while the built-in web server provides real-time diagnostics and configuration capabilities. Ideal for applications requiring distributed I/O in manufacturing, process control, or material handling, this adapter is built to withstand industrial environments with its robust enclosure and wide operating temperature range. Below are the detailed specifications derived from the product’s technical datasheet.
