(Summary description)One of electromagnetic relays and solid-state relays is afraid of shocks, the other is not afraid of shocks; the former is afraid of magnetism and the latter is afraid of induced electricity; one has low heat and the other has high heat; one is low in price and the other is high in price; the former is easy to replace and the latter is the opposite.

  Relays are divided into solid state relays and mechanical relays, so what is the difference between these two relays? Let’s take a look with the editor below.
  One of electromagnetic relays and solid-state relays is afraid of shocks and the other is not afraid of shocks; the former is afraid of magnetism and the latter is afraid of induced electricity; one is low in heat and the other is high in heat; one is low in price and the other is high in price; the former is easy to replace and the latter is the opposite.
  Solid-state relays and mechanical relays have their own strengths:
  1. Mechanical relays have strong overload capacity, and solid-state relays are not allowed to overload.
  2. When the mechanical relay is disconnected, it is physically disconnected, and there is no leakage current. Solid state relays are not physically disconnected and there is leakage current.
  3. The solid state relay has no mechanical components, so the switching speed is fast, and the number of switching is almost unlimited.
  4. The mechanical relay has mechanical components, so the switching speed is slow, the mechanical wear contacts burn, and the number of switching times is limited.
  5. Solid state relays are easily damaged when overloaded or struck by lightning.
  6. The safety life of the mechanical relay is long.
  The above six points are the differences between solid state relays and mechanical relays sorted out by the editor. I hope they will be helpful to everyone.
