Mitsubishi LY28S1A - Programmable Logic Controller

The Mitsubishi LY28S1A PLC offers a powerful combination of precision, compact design, and robust output handling for AC-based control applications. It features 8 integrated TRIAC digital outputs, supporting stable load control with a rated voltage of 100–240 VAC. This makes it ideal for switching resistive and inductive AC loads in industrial machinery. With 16 occupied I/O points, this module easily integrates into mid-sized automation systems without consuming excessive panel space.

Its dimensions—117 mm depth, 28.5 mm width, and 90 mm height—enable installation in compact control panels, while the use of screw terminals ensures vibration-proof, secure wiring in demanding environments. The unit weighs just 0.19 kg, yet is built to deliver rugged performance even in high-load scenarios. Its internal current consumption of 0.2 A makes it energy efficient, and the TRIAC output type provides smooth, silent operation for devices like lamps, heaters, and contactors.

Backed by the reputation of the Mitsubishi MELSEC-L Series, the LY28S1A is trusted by automation engineers for its long-term reliability, high-speed performance, and seamless compatibility with other Mitsubishi control components. It is frequently used in packaging lines, process equipment, HVAC control, and electrical panels across various industries.

The Mitsubishi LY28S1A PLC is widely used for controlling AC-powered components such as indicator lights, solenoid valves, heating coils, and alarm systems. Its TRIAC output ensures smooth, efficient switching without the noise or wear of mechanical relays, making it ideal for environments where durability and silence are critical.

In real-world applications, Indian engineers often use the LY28S1A to automate packaging conveyors, textile machines, HVAC zones, and lighting control systems in factories. The unit's compact design allows quick retrofitting in old panels, and the screw-terminal wiring helps reduce downtime during maintenance. Junior engineers benefit from its simplicity in Mitsubishi’s ladder logic environment, while senior engineers appreciate its consistent performance over long operating cycles.

From food processing units to automated testing stations, the Mitsubishi LY28S1A PLC delivers unmatched control reliability and seamless integration, especially in systems requiring quiet, reliable AC load switching. For engineers seeking a high-quality solution for AC control, the LY28S1A PLC remains a trusted component in Mitsubishi's automation lineup.
