Product Description

The QJ71FL71-B2 Module, part of the Mitsubishi FL71 Series, is an FL-net Communication Module designed for high-speed industrial network integration. It supports FL-net (OPCN-2) protocol, enabling real-time data exchange across controllers and devices within automation systems. The module operates on a 24 VDC power supply (range: 20.4–28.8 V) and functions reliably in temperatures from 0 to 55°C. It integrates seamlessly with Mitsubishi PLCs, providing compatibility with multiple I/O modules and supporting up to 64 nodes per network for scalable connectivity. Key features include plug-and-play configuration, error diagnostics, and collision detection for stable communication. Widely used in manufacturing, robotics, and process control industries, its advantages include robust performance, low latency, and interoperability with FL-net-compliant devices. However, it lacks native support for non-FL-net protocols, limiting flexibility in mixed-network environments. Compact in design, it requires no battery or display, focusing solely on efficient network management for industrial automation.
