Solid state relays are often used instead of electromechanical units in continuously switched AC applications where contact burn out is a problem. By using a photo-diac as the isolation element the low voltage input of the FK423 is completely isolated from the AC mains side. Additionally, the mains zero point at which the output triac is switched on makes the FK423 ideal for switching lighting and high inrush loads.
