The Mitsubishi expansion cable RC30B, with a cable length of 3.0 meters, is specifically designed for use with the MELSEC iQ-R series programmable logic controllers (PLCs). This cable facilitates reliable and high-speed data transmission between modular components within the automation system.

The MELSEC iQ-R series features an inter-module synchronization function, which enables multiple input/output modules and intelligent function modules to operate in precise timing alignment based on a shared synchronization cycle. This capability ensures that the input or output timing of designated modules is synchronized, allowing for coordinated and accurate control of machinery and processes.

By leveraging this synchronization function, users can achieve consistent and stable system performance, particularly in applications that demand high precision and repeatability. Additionally, when combined with CC-Link IE Field Network synchronous communication, the system can synchronize operation timing across multiple network nodes. This eliminates timing errors caused by network transmission delays, thereby enhancing overall system reliability and stability.

The simultaneous use of these synchronization technologies simplifies complex tasks that require synchronized actions across multiple devices. Typical applications include printing press operations such as cutting and folding processes, where precise timing is critical to maintaining product quality and operational efficiency.
