WebSolid state relays can be divided into AC SSR and DC SSR according to applications. Now take AC solid state relay as example to explain SSR working principle. As Figure 1 show, it is a AC SSR working principle diagram and the parts ①~④ form its main body. As a whole, SSR only has 2 input terminals (A & B) and 2 output terminals (C & D). WebThe AC relay works in the AC circuit. When the AC current passes through the coil, an alternating magnetic flux is generated in the iron core. Since the traction force (electromagnetic attraction) is the square of the magnetic flux φ is proportional, so when the current changes direction, the traction force does not change direction, always attracting …
