R32SFCPU-SET - Mitsubishi Programmable Controllers Melsec

The Mitsubishi R32SFCPU-SET PLC is designed for high-speed and high-precision control, equipped with a 320K step program memory and support for up to 4096 I/O points. It belongs to the MELSEC iQ-R Series, Mitsubishi's flagship platform for demanding industrial tasks. With a lightning-fast instruction cycle time of 0.98 ns (LD) and 1.96 ns (MOV), this SAFETY CPU is ideal for applications requiring real-time processing and strict safety compliance.

This model features an integrated Ethernet port (1x RJ45) for seamless communication and a built-in buffer battery to ensure data retention in power loss scenarios. Physically compact at just 27.8 mm wide and weighing only 0.2 kg, the R32SFCPU-SET is CE and UL/cUL compliant, ensuring international safety and quality standards. Its rugged design includes vibration resistance (IEC 60068-2-6), operation in temperatures from -10°C to 60°C, and IP20-rated housing, allowing deployment in tough environments with minimal maintenance.

Thanks to its natural convection cooling, low power dissipation of just 27W, and vertical operation capability, this PLC is energy-efficient and easy to integrate. Whether it's in a small control panel or a large-scale distributed control system, the R32SFCPU-SET delivers consistent performance and long-term durability.

The R32SFCPU-SET is purpose-built for use in safety automation systems across multiple industries such as packaging, automotive, food processing, and machine building. Its safety CPU architecture enables redundant monitoring and safe shutdowns, critical for applications like emergency stop circuits, guard door interlocks, and robotic safety zones.

In a packaging line, this Mitsubishi PLC ensures rapid decision-making for safety events while maintaining cycle times for conveyor controls. In automotive assembly, it helps manage complex interlocks between welding robots and safety fences. Its compact form factor makes it easy to mount in tight control cabinets, while high I/O density allows flexible configurations for growing systems. The built-in Ethernet interface simplifies SCADA or MES integration, making it a future-proof choice for digital factories.

For engineering students and maintenance professionals in India, the R32SFCPU-SET serves as an ideal case study in advanced PLC architecture—combining speed, safety, and energy efficiency. With plug-and-play scalability and reliable Mitsubishi build quality, it sets a benchmark for PLCs in mission-critical automation tasks.
