The Solid State Relay 120 DA is a robust and efficient electronic switching device engineered for high-power control applications. Unlike traditional electromechanical relays, it utilizes semiconductor components for switching, ensuring long operational life, silent operation, and resistance to mechanical wear. With an input control voltage range of 90–280 V AC, it provides flexible compatibility with various control systems.
On the output side, this relay supports load currents up to 120 A at operating voltages between 24–480 V AC, making it highly suitable for heavy-duty industrial applications such as resistive heating, motor control, HVAC systems, and lighting circuits. Its fast switching capability, low EMI, and high dielectric strength ensure stable performance even under demanding load conditions.
The Solid State Relay 120 DA is designed with safety and reliability in mind, incorporating features such as zero-cross switching to minimize inrush currents and heat dissipation. Its compact design, durable housing, and high insulation resistance make it an excellent choice for industrial automation, process control, and other environments where dependable and maintenance-free switching is critical.
