Q2MEM-1MBSN
Q2MEM-1MBSN module for Mitsubishi Q Series PLCs, providing 1MB memory expansion to enhance system data storage capacity and program management efficiency.

Product Description

The Q2MEM-1MBSN module is a Mitsubishi Q Series Memory expansion unit designed for PLC systems, delivering 1MB non-volatile storage for program and data retention. This PLC 1MB storage module connects directly to Q Series PLC base units via the MELSEC interface, enabling seamless integration with multiple expansion modules without onboard I/O ports. It operates at 24V DC (±10%) within an industrial temperature range of 0–55°C, making it suitable for automation, manufacturing, and process control. Key advantages include high reliability, plug-and-play compatibility, and an integrated lithium backup battery (120mAh) for memory preservation during power loss. Limitations include fixed storage capacity and no integrated display. Built for rugged environments, it ensures stable performance in critical applications requiring scalable memory solutions.
