Product Description

The Mitsubishi QJ71BR11 module is a versatile communication module within the MELSEC-Q series, designed for high-speed data exchange in industrial automation systems. As a MELSECNET/H network module, it supports a wide range of industrial protocols and enables seamless integration with up to 64 stations in a single network. The QJ71BR11 communication module operates on 24 VDC power (±10%) and functions reliably in temperatures from 0°C to 55°C, making it suitable for manufacturing, energy, and process control industries. It features a compact design without onboard I/O but provides dual communication ports (coaxial or optical fiber) for redundant network configurations. Key advantages include real-time data transmission, robust noise resistance, and compatibility with MELSEC-Q series PLCs. Its primary limitation is the requirement for specialized configuration tools. While lacking built-in battery or display interfaces, it excels in distributed control systems requiring stable, long-distance communication.
