The Mitsubishi QX50 PLC is a 16-point AC input module from the versatile MELSEC-Q Series, designed for environments where digital inputs are driven by 48V AC signals. It offers 16 integrated digital inputs with screw terminal wiring, making it suitable for monitoring field devices like push buttons, limit switches, or sensors operating on 48V AC supply. With a compact footprint of 27.4 mm width, 98 mm height, and 90 mm depth, it fits seamlessly into high-density control cabinets.
The unit's low internal current consumption of just 0.05 A ensures energy efficiency, while its durable construction supports long-term reliability under continuous industrial operation. Its screw terminal wiring offers vibration-resistant connections, commonly required in automotive, food processing, and textile automation sectors. The QX50 communicates effectively with other modules in the MELSEC-Q Series ecosystem, enabling scalable and modular automation architectures.
Backed by Mitsubishi Electric's global reliability and supported by GX Developer and GX Works platforms, the QX50 PLC ensures smooth integration and minimal configuration effort. Whether youβre expanding existing I/O capacity or standardizing control logic across AC-driven field devices, the QX50 delivers precision, compatibility, and performance. The Mitsubishi QX50 PLC is commonly used in Indian factories where digital inputs like push buttons, selector switches, and contact-based field devices operate at 48V AC. Its high input reliability ensures accurate response in packaging units, bottling plants, and process control panels.
Thanks to its screw terminal connections, wiring is secure and easy to maintain, even in dusty or vibration-heavy environments. Engineers prefer this module for retrofitting older machines that use AC logic, as it supports seamless integration with the rest of the MELSEC-Q Series. Students and junior maintenance staff benefit from the moduleβs diagnostic indicators and clear terminal layout, which simplify troubleshooting.
Whether you're designing a new panel or upgrading legacy machinery, the Mitsubishi QX50 provides reliable AC signal input capabilities for robust and scalable automation systems.
