The Mitsubishi FX5UJ-40MT/DSS PLC delivers high-performance control in a small footprint, offering engineers a reliable solution with advanced features tailored for mid-range automation tasks. Operating on a 24V DC power supply, it comes equipped with 48K steps of FLASH program memoryβensuring secure, fast, and non-volatile execution of complex logic routines. With 24 digital inputs and 16 transistor outputs utilizing source logic, this model supports a balanced I/O structure suited for digital motion control, sensor interfacing, and fast-switching loads.
The FX5UJ-40MT/DSS achieves real-time responsiveness with a cycle time of just 34 ns for both LD and MOV instructions, making it one of the fastest CPUs in its class. Its maximum I/O handling capacity extends up to 256 local points, allowing seamless integration into scalable control architectures. Built-in communication options include a RJ45 Ethernet port and a 2-wire RS-485 interface, enabling smooth data exchange across SCADA systems, HMIs, and other PLCs.
For durability and energy-conscious deployments, it supports stable operation in environments up to 55Β°C, with a total power consumption of only 35W. The compact and robust enclosure, weighing just 583 grams, is CE compliant and fits easily into space-constrained cabinets with an IP20 protection rating. With its integrated EMC filtering, vibration resistance (1 gn), and support for up to 240V output at adjustable switching frequencies from 2β16 kHz, the FX5UJ-40MT/DSS is a trusted choice for industrial automation systems requiring performance, communication, and efficiency. Visit the official Mitsubishi FX5UJ product page for full documentation and specifications.
The FX5UJ-40MT/DSS is ideal for high-speed packaging machines, pick-and-place automation, textile drives, and standalone equipment in food processing, bottling, or labeling. Its fast transistor outputs and Ethernet communication make it well-suited for synchronized motion control and real-time data logging.
For example, in a conveyor system, the PLC can monitor sensor inputs for product detection, activate outputs for actuator control, and simultaneously relay machine data to SCADA over Ethernet. Its 24V DC design ensures compatibility with modern control panels, while the source-type outputs simplify integration with solid-state relays and opto-isolators. The FLASH memory retains program logic securely even during power loss, reducing downtime and simplifying restarts.
Maintenance teams appreciate its robust architecture and low power consumption, while engineering students find it intuitive for learning ladder logic and industrial communication. Whether you're replacing outdated relay logic systems or designing smart control panels from scratch, the Mitsubishi FX5UJ-40MT/DSS offers a future-ready, compact, and powerful control solution trusted across industries.
