Product Description

The Mitsubishi QD81MEM-8GBC module, a member of the MELSEC-Q series, is a high-performance memory extension module designed for industrial automation systems. It supports 32 input/output points via direct connection to 8 expansion modules and includes Ethernet and RS-232 communication interfaces. Operating at 24V DC with a temperature range of -10°C to 55°C, this module is widely used in manufacturing, energy, and logistics for robust data handling. Key advantages include 8GB flash memory, error-logging capabilities, and compatibility with MELSEC-Q PLCs. However, it lacks built-in analog I/O support and requires separate configuration tools. The QD81MEM-8GBC features a backup lithium battery (2000mAh) for data retention and compact dimensions (24mm width) for space-constrained installations, though it has no integrated display or proximity sensing functions.
