Mitsubishi QX80 - Programmable Logic Controller

The Mitsubishi QX80 PLC features 16 integrated DC digital inputs with a minus common configuration, making it ideal for structured input signal management in industrial environments where consistent grounding is required. Operating on a standard 24 V DC rated input voltage, the module supports wide compatibility with industrial sensors, switches, and dry-contact devices. It uses screw terminal wiring, ensuring secure connections that can withstand vibrations common in control panels and machinery. This PLC input module is compact and efficient, with a form factor measuring just 27.4 mm in width, 98 mm in height, and 90 mm in depth, allowing it to fit easily into space-constrained electrical cabinets. Despite its rugged build, the module maintains a moderate weight of 144 grams, making installation and replacement hassle-free. It occupies 16 I/O points and draws a reliable 0.5 A of internal current, offering stable performance without overloading the system’s power distribution. As part of the trusted MELSEC-Q Series, it integrates smoothly with other Mitsubishi I/O, communication, and CPU modules, enabling seamless scalability. The QX80 is widely used in applications such as machine tools, conveyors, packaging lines, and process equipment—where accurate and noise-resistant input handling is essential. Known for its long-term reliability, secure wiring, and consistent performance, the Mitsubishi QX80 PLC is a preferred choice for system integrators and OEMs across industries. The Mitsubishi QX80 PLC is perfectly suited for industrial control applications that require precise input detection and strong signal stability. It is commonly installed in assembly lines, automated testing rigs, and factory floor machines that depend on timely input feedback from sensors, push buttons, and limit switches. Indian maintenance engineers value its minus common wiring approach for improving signal grounding consistency and reducing false triggers due to electrical noise. With its 24 V DC input rating and rugged terminal screw connections, the QX80 ensures dependable performance even in dusty or high-vibration environments. For junior automation engineers and students, this module is a practical entry point to understanding how industrial PLCs collect real-world input data for logic processing. Whether you're expanding a legacy MELSEC-Q system or building a new industrial setup, the QX80 delivers accuracy, safety, and integration flexibility—making it a long-term asset in any Mitsubishi PLC installation.
