Mitsubishi QJ71E71-100 MELSEC-Q Ethernet Communication Module
Product Overview
Mitsubishi QJ71E71-100 is a MELSEC-Q series Ethernet communication module used in PLC network systems, factory automation networks, machine control cabinets, and industrial data communication applications. It allows a Q series PLC system to connect with Ethernet-based devices, supervisory systems, HMIs, engineering stations, data collection systems, and plant-level automation networks.
This model is one of the high-value MELSEC-Q communication modules because Ethernet communication is widely used in industrial control systems. For maintenance teams, QJ71E71-100 is commonly searched when an existing PLC network module fails, when communication with an HMI or SCADA system is interrupted, or when a Q series PLC system needs Ethernet communication replacement.
