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

The LRSSR-DA DC Control AC Solid State Relay is a high-performance switching solution designed for demanding industrial and automation applications. With an impressive 40-amp current capacity, this relay handles heavy loads with ease, making it ideal for motor control, heating systems, and other high-current applications. The relay accepts a wide DC input voltage range of 3 to 32V, ensuring compatibility with a broad variety of controllers, microcontrollers, and sensors. Its optically isolated input design provides safe and reliable separation between the control and load circuits, protecting sensitive control electronics from high-voltage interference. The built-in zero-crossing switching function minimizes electrical noise and reduces stress on connected loads, helping to extend their operational lifespan. Rated for 240VAC output at 50Hz, this relay is well-suited for resistive load applications. The rugged construction includes built-in overheat protection for stable, long-term performance. A clear protective cover shields the terminal connections, adding an extra layer of durability and safety to the unit.
