Water tank automatic water supply circuit diagram

The picture shows the automatic water filling circuit diagram of the water tank . IC is PSSR type AC solid state relay , which is a new type of AC non-contact relay developed on the basis of SSR solid state relay. Compared with SSR, it not only has the active driving function of SSR, but also has passive driving and Load power drive function. PSSR solid state relay has the advantages of simple structure, reliable operation and low noise.
