Mitsubishi QY40P - Programmable Logic Controller

The Mitsubishi QY40P PLC delivers efficient and accurate digital output control, making it a reliable choice for industrial-grade automation applications. As a transistor output (sink logic) module, it features 16 integrated digital outputs and occupies 16 I/O points within the system. This makes it ideal for controlling actuators, relays, and interface devices that operate on a 12–24V DC power supply. With a rated load voltage of 12/24 VDC, it ensures safe and consistent switching across a range of industrial loads.

Compact and lightweight, the QY40P measures just 90 mm in depth, 27.4 mm in width, and 98 mm in height, with a weight of only 0.16 kg. The screw-type wiring terminals offer secure connectivity and are easy to maintain even in high-vibration environments. Its low internal current consumption of 65 mA ensures energy-efficient operation, and the output response is fast, stable, and noise-resistant—ensuring accurate signal execution in real-time control systems.

Trusted by engineers worldwide, the Mitsubishi QY40P integrates seamlessly with MELSEC-Q Series PLCs and is backed by Mitsubishi’s legacy of industrial reliability. Its robust transistor switching, durable design, and compatibility with a wide range of automation components make it an essential building block for control panels, machinery, and manufacturing systems.

The Mitsubishi QY40P PLC is widely used in factory automation systems that require fast and reliable switching of digital outputs. It's ideal for driving solenoids, indicator lights, small motors, and other output devices in packaging lines, conveyor systems, and automated assembly machines.

Its transistor output (sink type) makes it particularly effective in applications where output response time and electrical noise immunity are critical. For example, engineers often deploy the QY40P in bottle-filling systems, robotic cells, and pick-and-place machines—where precision and timing cannot be compromised.

Thanks to its modular design, compact size, and reliable output performance, the Mitsubishi QY40P integrates effortlessly into both new and retrofit projects using the MELSEC-Q Series. Whether you're building a custom control panel or scaling an existing PLC network, this Mitsubishi PLC ensures long-term durability, seamless system compatibility, and superior performance under demanding industrial conditions.
