The Omron S3D2-AK solid-state relay delivers reliable, silent AC load switching in industrial automation and control panels, ideal for replacing mechanical relays in heaters, motors, and lighting circuits. Its 24 V DC control input switches an AC load up to 240 V AC, with a load current typically in the 2–10 A range (model dependent), and it uses zero-cross switching with optical isolation between input and output. The unit mounts on DIN rails or panels and is cooled by natural convection, designed for industrial load switching and control. Common replacements include Omron G3NA-210B, Omron S3D2-A, and Crydom D2425.
