Product Description
The Q65B is an extension rack/backplane designed for Mitsubishi MELSEC‑Q (QnU) series PLC systems. It provides a dedicated power supply unit slot and five I/O module slots, enabling expansion of existing Q-series installations while maintaining system integrity and bus performance. The unit serves as a backplane for additional modules in distributed or larger control architectures, ensuring reliable interconnection and power distribution across the rack. It is suitable for industrial automation environments requiring scalable PLC configurations, with mechanical design matched to the Q-series ecosystem for straightforward installation and wiring.
