Mitsubishi RY20S6 - Programmable Logic Controller

The RY20S6 is a robust PLC module developed by Mitsubishi Electric, featuring 16 integrated TRIAC outputs for seamless switching of AC loads. Operating within a rated load voltage range of 100–240 VAC, it is ideal for controlling actuators, indicator lamps, and solenoids in high-demand industrial setups. With 0.28 A internal current consumption, this module ensures energy-efficient operation and long-term system stability. The compact form factor — just 27.8 mm wide, 131 mm deep, and 0.24 kg in weight — enables it to fit effortlessly into dense control cabinets. The screw terminal wiring ensures a secure electrical connection, while its design occupies only 16 I/O points on the Mitsubishi PLC, conserving system resources.

Engineered as part of the advanced MELSEC iQ-R Series, the RY20S6 ensures maximum system reliability with its streamlined configuration and compatibility across a broad range of industrial applications. It meets global standards in safety, flexibility, and expandability, making it a favorite among automation professionals. Maintenance engineers trust this Mitsubishi PLC for its consistent performance and easy diagnostics, while OEMs appreciate its integration capability in modular architectures. The Mitsubishi PLC RY20S6 is widely used in factory automation, especially in control panels for packaging systems, conveyor belts, and automatic test machines. In real-world use, it controls AC loads like motor starters, pilot lamps, and relays where fast and safe switching is critical. Engineers appreciate the simplicity of screw wiring, while its ability to handle 16 TRIAC output points allows central control without external expansion. It reduces panel wiring, minimizes response lag, and simplifies troubleshooting, helping maintenance teams improve uptime.

For junior engineers and students, the RY20S6 is an ideal example to study AC switching logic using a PLC. It clearly demonstrates how industrial outputs are managed through PLC programming and hardware interfaces. This builds a strong foundation in PLC applications, I/O mapping, and safety circuits. Whether used in education, retrofitting older panels, or scaling smart factories, this module offers dependable performance backed by Mitsubishi’s reputation in automation. If you're looking for a compact, reliable, and scalable PLC output module, the Mitsubishi PLC RY20S6 is a proven solution that delivers both efficiency and longevity.
