Mitsubishi SD1T0A-A (SD-1T0A-08) SD Memory Card Module – MELSEC iQ-R/Q Series
Imagine a critical production line halting mid-shift because a PLC program was lost after a power surge — no backup, no recovery path, hours of downtime, and thousands in lost output. In high-stakes industrial environments, the absence of a reliable program storage and data-logging solution is not a minor oversight; it is a single point of failure that can cascade into plant-wide disruption. The Mitsubishi SD1T0A-A (SD-1T0A-08) SD Memory Card Module exists precisely to eliminate that risk, providing a robust, field-proven storage medium that keeps your automation system running with confidence.
The SD1T0A-A is a 1 GB industrial-grade SD memory card engineered specifically for Mitsubishi Electric’s MELSEC iQ-R and MELSEC-Q Series programmable logic controllers. Within the MELSEC ecosystem, this module occupies the essential role of non-volatile program storage, data logging, and system backup — functions that are indispensable in any serious automation architecture. Mitsubishi Electric’s MELSEC iQ-R platform is recognized globally as one of the most reliable and scalable PLC families in discrete and process manufacturing, and the SD1T0A-A is the certified storage solution that underpins its data integrity.

- Industrial Durability: Designed to withstand the vibration, temperature variation, and EMI conditions typical of industrial control panel environments.
- Plug-and-Play Compatibility: Certified for direct insertion into MELSEC iQ-R and Q Series CPU SD card slots — no additional configuration hardware required.
- Scalable Storage: 1 GB capacity accommodates large ladder logic programs, structured text, function block diagrams, and extensive data log files.
Industry & Equipment Applications
- Automotive Manufacturing: Body welding lines, paint shop conveyors, and assembly robot controllers requiring reliable program backup.
- Food & Beverage Processing: Batch control systems where recipe data and process logs must be retained for regulatory compliance.
- Semiconductor Fabrication: Cleanroom automation where unplanned downtime carries extreme cost penalties.
- Water & Wastewater Treatment: Remote pump stations and SCADA-integrated PLCs requiring autonomous boot-from-card operation.
- Pharmaceutical Production: GMP-compliant data logging for audit trails and batch records.
- Steel & Metal Processing: Rolling mill and furnace control systems with high-vibration environments.
System Integration & Compatible Parts
The SD1T0A-A is compatible with the following Mitsubishi Electric MELSEC platforms and commonly paired components:
- MELSEC iQ-R Series CPU modules (R04CPU, R08CPU, R16CPU, R32CPU, R120CPU, etc.)
- MELSEC-Q Series CPU modules with SD card slot (Q03UDECPU, Q06UDEHCPU, Q13UDEHCPU, etc.)
- Mitsubishi GX Works3 / GX Works2 engineering software for program read/write operations
- MELSEC iQ-R Series power supply modules (R61P, R62P) and base units
- Mitsubishi GOT2000 Series HMI for integrated data visualization
When building or expanding a MELSEC control system, the SD1T0A-A pairs naturally with CPU modules, network modules (RJ71EN71, RJ71GF11-T2), and I/O modules to form a complete, redundancy-ready automation solution.

Frequently Asked Questions
- Q: Is the SD1T0A-A compatible with all MELSEC iQ-R CPU modules?
- A: The SD1T0A-A is designed for MELSEC iQ-R and Q Series CPUs equipped with an SD card slot. Always verify compatibility against your specific CPU model’s hardware manual before ordering.
- Q: Can I use a standard consumer SD card instead of the SD1T0A-A?
- A: Mitsubishi Electric recommends using only certified SD cards (such as the SD1T0A-A) to ensure reliable operation. Consumer-grade SD cards may not meet the industrial temperature, vibration, or write-endurance specifications required by MELSEC systems.
