Mitsubishi SRAM Memory Card – Q1MEM-256S

The Mitsubishi Q1MEM-256S is a high-performance SRAM-based memory card designed for use with Mitsubishi programmable logic controllers (PLCs), particularly from the MELSEC-Q series.

Key Features:

●Memory Type: Static RAM (SRAM) – provides fast read/write access and reliable data retention.

●Storage Capacity: 256 KB (kilobytes), suitable for storing program data, device comments, and file registers.

●Battery Backup: Integrated battery backup ensures data retention even when the PLC is powered off, preserving critical data during power loss.

●Compact Design: Standard memory card form factor for easy installation and replacement in compatible PLC units.

●High Reliability: SRAM technology offers stable and consistent performance, with no wear-out issues associated with flash memory.

Typical Applications:

●Parameter storage and backup for PLC systems.

●Extended data logging and recipe storage.

●Backup of device comments and program files.

●Temporary data buffering and high-speed data transfer in automation processes.

Compatibility:

Designed for use with Mitsubishi MELSEC-Q series PLCs that support SRAM memory cards, ensuring seamless integration and reliable operation in industrial automation environments.

Note: The battery should be replaced periodically to maintain data retention performance.
