MITSUBISHI AJ71UC24 CC-Link Communication Module – MELSEC-A Series
When a CC-Link communication module fails on the production floor, the entire network of remote I/O stations, inverters, and intelligent devices goes silent. Conveyor lines halt, robotic arms freeze mid-cycle, and operators are left with no visibility into field device status. Every minute of unplanned downtime translates directly into lost output and costly emergency maintenance calls. The MITSUBISHI AJ71UC24 is the purpose-built solution that keeps your MELSEC-A PLC system’s communication backbone running without interruption.
The AJ71UC24 occupies a critical position within the MELSEC-A series as a dedicated CC-Link master/local station communication module. Designed for Mitsubishi Electric’s proven MELSEC-A programmable controller platform, this module has earned its place in thousands of industrial automation installations worldwide — from automotive body shops in Japan to chemical processing plants in Europe — precisely because it delivers deterministic, high-speed field network communication in the most demanding environments.
