The Mitsubishi QX28 PLC is designed to capture input signals from AC-powered field devices such as limit switches, relays, and push buttons. It features 8 integrated digital inputs across 16 occupied I/O points, delivering reliable performance within the MELSEC-Q SERIES architecture. This module supports a wide rated input voltage of 100–240V AC, offering excellent compatibility in both domestic and industrial electrical environments. With a modest internal current consumption of 0.05 A, it contributes to energy-efficient system performance.
The module's form factor—just 90 mm in depth, 27.4 mm in width, and 98 mm in height—allows for easy installation in compact panels. It features screw terminal wiring, ensuring strong electrical connections and minimal signal loss even in vibration-prone or high-heat environments. Weighing approximately 165 grams, the QX28 is lightweight yet rugged enough for heavy-duty industrial use.
As part of Mitsubishi’s proven MELSEC-Q SERIES, the QX28 is trusted by automation professionals worldwide for its durability, simplicity, and long service life. It integrates seamlessly into modular PLC setups, making it ideal for panel builders, OEMs, and control engineers working with AC-powered equipment.
The Mitsubishi PLC QX28 is well-suited for motor control centers, packaging lines, power distribution panels, industrial HVAC systems, and conveyor-based automation. It is especially useful in environments where sensors and actuators run on 100–240V AC and require direct interface with the PLC.
Engineers across Indian manufacturing units value the QX28 for its ability to handle AC inputs without additional signal converters. Maintenance teams benefit from its secure screw terminals and easy replacement process. For automation students and new technicians, this module offers a practical learning experience in AC-based input signal processing and wiring safety standards.
If your automation setup includes AC-powered switches or field devices, the Mitsubishi QX28 PLC provides a durable, tested, and easy-to-integrate solution that helps ensure reliable system operation in real-world industrial environments.
