LRSSR-DA DC Control AC SSR-40DA Solid State Relay (40A)

The LRSSR-DA Solid State Relay is a reliable and high-performance switching solution designed for demanding industrial and automation applications. With a robust 40-amp current rating, this DC control AC relay handles heavy loads with ease, making it ideal for motor control, heating systems, and other power-intensive setups. The DC input range of 3–32VDC allows seamless integration with a wide variety of low-voltage control systems, while the 240VAC output at 50Hz ensures compatibility with standard AC loads. The optically isolated design provides safe signal separation between the input and output circuits, protecting sensitive control electronics from high-voltage interference. A built-in zero-crossing switching function minimizes electrical noise and reduces stress on connected loads, extending their operational lifespan. The compact solid state construction eliminates mechanical contacts, resulting in silent, vibration-free operation and exceptional long-term durability. A clear protective cover shields the terminal connections, adding an extra layer of safety during installation and use.
