Product Description

The QJ71FL71 module is an FL-net communication module designed for Mitsubishi's MELSEC FL-net interface, enabling seamless integration within industrial automation systems. This module supports FL-net (OPCN-2) protocol, facilitating real-time data exchange between controllers, I/O devices, and sensors over a 100BASE-TX Ethernet network. It operates at 24 V DC ±10% with a temperature range of 0–55°C, ensuring reliability in harsh environments like automotive manufacturing, robotics, and process control. The QJ71FL71 lacks built-in I/O points but connects up to 64 nodes via FL-net, offering high-speed synchronization and scalability. Key advantages include low latency, compliance with IEEE 802.3u standards, and compatibility with MELSEC-Q series PLCs. Limitations involve dependency on external power and no onboard battery or display. Screen size and detection distance are not applicable as it functions solely as a network interface module.
