Solid State Relay 40 AA

The Solid State Relay 40 AA is a robust and efficient switching solution designed for controlling AC loads with precision and reliability. Unlike traditional electromechanical relays, this SSR offers contactless switching, which eliminates mechanical wear and provides extended operational life. With a rated load current of 40A and wide input control voltage compatibility, it is suitable for high-capacity applications where consistent performance is critical.

Built with an optically isolated input, the relay ensures safe separation between control and load circuits, enhancing system safety and minimizing electrical interference. It features zero-cross switching technology, which reduces inrush currents and electrical noise, making it ideal for sensitive equipment and environments requiring stable performance. The fast response time and low input trigger current ensure seamless integration into automation systems, PLCs, and microcontroller-based controls.

The Solid State Relay 40 AA is widely used in industrial automation, heating control, packaging machines, lighting systems, and motor drives. Its compact design, screw terminal connections, and durable housing make installation straightforward while maintaining excellent heat dissipation. With no moving parts and high resistance to shock and vibration, this relay is a reliable choice for demanding environments, ensuring smooth and maintenance-free operation over long service cycles.
