Product Description

The QD81MEM-2GBC memory module is a 2GB PLC extension memory designed for MELSEC Q series storage expansion. It integrates seamlessly with Q-series PLCs, supporting direct connection to base units via the system bus without requiring additional I/O allocation. This module operates at 5VDC (±5%) and functions within industrial temperature ranges (0 to 55°C). Ideal for complex automation, data logging, and motion control applications, it enhances program capacity and data storage in manufacturing environments. Key advantages include plug-and-play compatibility, high-speed data access, and robust error detection, though it lacks standalone operation capabilities. The module uses a non-replaceable backup lithium battery (typ. 190mAh) to retain data during power outages. It does not feature a screen or physical input/output ports, focusing exclusively on memory expansion.
