Mitsubishi QX90H - Programmable Logic Controller

The Mitsubishi QX90H PLC is designed for rapid and accurate signal detection, offering 16 high-speed digital inputs optimized for 5V DC logic signals. It supports screw terminal wiring for robust and vibration-resistant connections, making it a reliable solution for dynamic environments like servo control, robotic systems, and high-speed machine feedback loops. This input module is part of the powerful MELSEC-Q Series, which ensures seamless compatibility with other Mitsubishi Electric automation components and software platforms like GX Works and GX Developer.

Compact and efficient, the QX90H measures just 27.4 mm (W) × 98 mm (H) × 90 mm (D) and weighs only 0.14 kg, enabling high-density panel integration. With an internal current consumption of 0.08 A and support for 16 I/O points, this module is ideal for systems requiring fast logic-level input processing with minimal space and power usage. It’s engineered to maintain stable performance even in electrically noisy or demanding industrial environments.

Whether you're deploying the QX90H in semiconductor manufacturing, motion-based systems, or precision measurement applications, it offers the performance, speed, and signal clarity needed for mission-critical control. Built by Mitsubishi Electric, this module is backed by global support, quality assurance, and detailed documentation.

The Mitsubishi QX90H PLC is purpose-built for applications requiring ultra-fast input signal detection at 5V DC. It is commonly used in automation environments where timing and feedback must be accurate to the millisecond—such as in high-speed packaging machines, encoder-based positioning systems, pick-and-place robots, and optical inspection setups.

Its screw-type terminal design offers secure, maintenance-friendly wiring that holds up well in panels exposed to vibration or thermal expansion. Engineers prefer this module when integrating TTL-level logic devices or when signals from fast-reacting components must be captured and processed instantly by the PLC CPU. Despite its compact footprint, it handles input signals reliably even under continuous operation.

If you're building or expanding a MELSEC-Q based automation panel that requires quick response to low-voltage logic signals, the Mitsubishi QX90H PLC is a proven, high-speed input solution trusted across industries for precision and reliability.
