1794-ACN15 Product Description Allen-Bradley 1794-ACN15, also named Flex I/O ControlNet adapter module, is a fieldbus communication adapter for 1794 Flex I/O distributed system. It is designed to connect Flex I/O modules to ControlNet network, supporting real-time I/O data transmission for old automation equipment renovation.

This module delivers reliable bus communication for industrial control tasks. The bus communication supports ControlNet protocol with 5Mbps transmission speed. The bus communication realizes producer-consumer data exchange between controller and remote I/O. Stable bus communication completes distributed I/O signal interaction for factory production lines.

The built-in signal processing achieves steady data exchange. The data exchange manages up to 8 Flex I/O modules on local backplane. The data exchange converts ControlNet bus signal into backplane I/O data. Accurate data exchange ensures synchronous signal reading according to control programs.

DIN rail mounting structure brings convenient system expansion. System expansion can be directly clipped on standard cabinet DIN rail. System expansion links ControlNet network via BNC coaxial connector. Flexible system expansion is widely used for legacy Flex I/O system spare replacement.

1794-ACN15 supports network diagnosis and module status monitoring function, equipped with BNC port for ControlNet coaxial wiring. It has LED status indicators for network link and fault diagnosis. Widely applied in material handling machines, packaging equipment and traditional assembly lines. This product is discontinued by Rockwell Automation, mainly supplied as industrial spare parts, complying with Flex I/O industrial control standards.
