Product Description

The Mitsubishi Q2MEM-4MBF Module is a Melsec Q Series 4MB Memory expansion unit designed to enhance PLC storage capabilities. This Q2MEM-4MBF PLC Memory Module integrates seamlessly with Q Series CPUs via the base unit, offering 4MB of non-volatile memory for program and data storage. It operates on a 24VDC power supply (range: 20.4–28.8VDC) and functions within an industrial temperature range of 0–55°C. Compatible with Melsec Q Series systems, it supports high-speed data processing and reliable retention without requiring external communication interfaces. Ideal for industrial automation, manufacturing, and process control applications, its key advantages include robust durability, easy integration, and extended data preservation. A potential limitation is its fixed capacity, which may require additional modules for larger systems. The module lacks a built-in screen or battery but relies on the PLC’s power for sustained operation.
