Product Description
Product Overview
The Allen-Bradley 1771-ACN15 is a 1771 ControlNet 1.5 Adaptor Module designed for the PLC-5 system, a legacy programmable logic controller platform widely used in industrial automation. Manufactured by Allen-Bradley, a brand under Rockwell Automation renowned for its industrial control solutions, this module serves as a network interface between 1771 I/O modules in a remote chassis and a ControlNet scanner port. It facilitates high-speed data transfer at 5 Mbps, supporting diagnostics and communication with remote I/O devices over the ControlNet network. The 1771-ACN15 features a single ControlNet connector and a Network Access Port (NAP) for local programming and maintenance, making it suitable for applications such as manufacturing, process control, and distributed I/O systems. Discontinued as of July 31, 2012, it remains critical for maintaining older PLC-5 installations, with migration paths recommended to newer Rockwell Automation solutions like Logix platforms.
