The Mitsubishi QH42P PLC combines 32-point digital input and 32-point transistor output in a single high-performance module. Designed for seamless integration into the MELSEC-Q Series platform, this I/O combined module operates on a 12–24V DC power supply and supports sink output logic for fast, accurate signal control. With a compact form factor of 27.4 mm (W) × 98 mm (H) × 90 mm (D) and a durable build of 137 grams, it helps engineers save space while enhancing reliability in tightly packed cabinets.
The QH42P is engineered with connector-based wiring, simplifying panel setup and maintenance. Its internal current consumption of just 0.13 A ensures energy-efficient performance, while its rated input and output voltage of 24V DC aligns with most industrial automation standards. Whether managing sensors, actuators, or relays, this module delivers stable, synchronized operations across all connected devices. With a total of 32 I/O points assigned on the PLC, it allows fast data exchange and cycle execution.
Built by Mitsubishi Electric—a global leader in factory automation—the QH42P is backed by extensive documentation, international certifications, and long-term reliability across industries like packaging, printing, bottling, and material handling. This module reflects Mitsubishi’s commitment to quality, speed, and space-saving control solutions.
The QH42P PLC from Mitsubishi is widely used in compact automation panels where both input sensing and output control need to be tightly integrated. It is ideal for industrial machines that require synchronized I/O functions—such as bottling units, textile machinery, small CNC stations, and inspection systems.
For example, in a packaging plant, the input section of the QH42P receives signals from proximity sensors or photoelectric sensors to detect product positions. Simultaneously, the output triggers solenoids or pneumatic cylinders to control gates, pushers, or actuators in real time. Its low current consumption and compact size make it well-suited for high-density PLC cabinets and embedded controller panels.
Whether you are retrofitting an old system or developing a new automation line, the Mitsubishi QH42P PLC offers dependable I/O performance, simplified wiring, and seamless scalability. Its balanced integration of input and output in a single module ensures less wiring, fewer errors, and faster commissioning time—all critical in today’s high-speed manufacturing environments.
