Allen Bradley 1794-ACN15 ControlNet Adaptor Module

The AB 1794-ACN15 is a ControlNet adapter module for the FLEX I/O system, enabling real-time communication between distributed I/O modules and ControlLogix or PLC-5 controllers via ControlNet networks. Operating on 24V DC, this adapter supports up to 8 FLEX I/O modules per node and facilitates deterministic I/O data exchange with high-speed update rates.

Designed for distributed applications where panel space is limited, the 1794-ACN15 offers a compact and modular design, allowing flexible expansion across machine control, material handling, and process systems that demand robust ControlNet integration.
