Product Description

The Mitsubishi QD81MEM-1GBC, also known as the Melsec 1GB Memory Module, is a high-capacity memory expansion module designed for industrial automation systems. This QD81MEM-1GBC Memory Module integrates seamlessly with Mitsubishi's Melsec-Q series PLCs, providing 1GB of non-volatile storage for data logging, program backup, and system parameter retention. It operates within a wide voltage range of 5VDC ±5% and supports industrial temperature ranges from 0°C to 55°C. The module interfaces via a dedicated high-speed bus, enabling direct communication with up to 4 linked modules without additional interface units. Its rugged design suits harsh manufacturing environments, particularly in automotive, robotics, and process control industries. Key advantages include error-proof data retention, quick access speeds, and compatibility with Mitsubishi's GX Works2 software. A built-in lithium battery (CR1025 type) ensures data preservation during power interruptions. While optimized for industrial scalability, it requires proprietary configuration tools and lacks standalone networking capabilities. No integrated display or sensing components are included.
