The Mitsubishi QX42-S1 PLC is designed to support large-scale signal acquisition with 64 integrated digital inputs, operating at a rated input voltage of 24 VDC using plus common logic. As part of the reliable MELSEC-Q Series, this input module offers fast signal response, minimal wiring complexity, and seamless integration into Mitsubishi’s modular PLC architecture.
With a compact footprint of 27.4 mm (W) × 98 mm (H) × 90 mm (D) and a solid build weighing only 141 grams, the QX42-S1 enables engineers to design dense, space-efficient control panels. Its connector-type wiring allows for clean cable management and quick installation, reducing setup time. The module consumes only 75 mA of current internally, making it energy-efficient despite supporting a high input count. It occupies 64 I/O points on the PLC, making it an ideal choice for applications that require a large number of digital signals to be monitored with precision.
Built with Mitsubishi Electric’s long-standing reputation for automation excellence, the QX42-S1 is trusted for critical systems in automotive manufacturing, logistics automation, and process control. It supports GX Developer and GX Works platforms, offering engineers a familiar configuration environment and long-term flexibility. With fast diagnostics, low maintenance needs, and globally supported documentation, the Mitsubishi QX42-S1 PLC is a dependable solution for modern control systems.
The QX42-S1 PLC module is ideal for automation systems that require centralized input control for high-volume digital signals. It is especially useful in applications like packaging lines, automotive welding cells, and warehouse automation where multiple sensors, interlocks, or pushbuttons need to be monitored simultaneously.
For example, in automotive assembly, the QX42-S1 can capture status from dozens of sensors, including door position, tool presence, and safety gates. In conveyor systems, it collects real-time inputs from photoelectric sensors, limit switches, and emergency stops to ensure smooth and safe operation. Its compact design and efficient wiring make it a preferred solution for space-constrained panels in fast-moving industrial environments.
Whether you're designing a new smart panel or expanding an existing PLC setup, the Mitsubishi QX42-S1 PLC delivers high-density input capability, fast response, and trusted reliability—making it a valuable asset in modern automation infrastructure.
