PLC Program Storage Solution – Mitsubishi Electric Q2MEM-32MBA | MELSEC-Q Series
Where This Product Is Used
The Mitsubishi Electric Q2MEM-32MBA is a 32MB Flash Memory Card engineered for demanding industrial environments where reliable program storage and fast data access are non-negotiable. Engineers specify this module across a wide range of sectors:
- Automotive Manufacturing: Body-in-white welding lines, paint shop conveyors, and engine assembly stations running complex MELSEC-Q multi-CPU configurations rely on the Q2MEM-32MBA to store large ladder and structured-text programs with zero data loss during power cycling.
- Food & Beverage Processing: High-speed filling, capping, and labeling machines use this card to retain recipe programs and batch parameters, enabling rapid product changeovers without re-downloading from an engineering workstation.
- Energy & Utilities: Substation automation panels and water treatment SCADA systems use the Q2MEM-32MBA as a secure backup medium, ensuring control logic is instantly recoverable after a CPU replacement in the field.
- Semiconductor & Electronics Fabrication: Cleanroom equipment controllers store motion profiles and process sequences on this card, supporting hot-swap CPU maintenance without production downtime.
- Material Handling & Logistics: Automated storage and retrieval systems (AS/RS) and sorter controllers use the card to distribute identical programs across multiple Q-series CPUs on the same rack.

Why Engineers Specify This Model
- Battery-Free Flash Storage: Unlike SRAM cards, the Q2MEM-32MBA retains data indefinitely without a backup battery, eliminating the risk of program loss from battery depletion during long shutdowns or storage.
- Large 32 MB Capacity: Accommodates extensive ladder programs, structured text, function blocks, and comment data for complex multi-axis or multi-process applications without capacity constraints.
- Plug-and-Play CPU Replacement: Insert the card into a replacement CPU and power on — the Q-series CPU automatically reads the program, dramatically reducing MTTR in critical production environments.
- Genuine OEM Reliability: Manufactured to Mitsubishi Electric’s stringent quality standards, ensuring full compatibility with GX Works2 / GX Works3 and Q-series system firmware.
- Compact Form Factor: Standard PC Card Type II interface fits all Q-series CPU memory card slots without adapters or modifications.

Application-Specific FAQ
Q: Can the Q2MEM-32MBA be used with Q02CPU (standard, non-H)?
A: Compatibility depends on CPU firmware version. The Q2MEM-32MBA is primarily rated for Q02HCPU and higher. Contact us to confirm.
Q: Does this card support both program storage and file register storage simultaneously?
A: Yes. The Q-series CPU can partition the Flash card to store both program memory and file register (ZR) data, subject to total capacity limits.
Q: Is a battery required to maintain data?
A: No. The Q2MEM-32MBA uses Flash ROM technology — non-volatile, retains data without any battery.
Q: Can I write to this card directly from GX Works2?
A: Yes. GX Works2 and GX Works3 both support writing programs directly to the Q2MEM-32MBA via the CPU’s memory card slot.
Q: What is the lead time for this part?
A: In-stock units ship within 1–3 business days. Out-of-stock lead time is typically 2–4 weeks. Contact us for real-time availability.
