    Tips: Why does SSR has advantages over EMR?

    SSR is a new type of non-contact switch composed of solid state electronic components, and achieve the purpose of connecting and disconnecting circuits without contact and sparking by virtue of those electronic components (such as switching transistors, triacs and other semiconductor components). Therefore, it is also known as non-contact switch. Compared with the previous Electromechanical Relay (EMR), the SSR has no moving mechanical parts and no mechanical actions during its operation. It has advantages over EMR, such as fast response, high reliability, long life (SSR’s on-off times are a hundred time more than those of average EMR by 106 times), no noises, shock-proof, mechanical shock resistance, good moisture-proof and mildew-proof, anti-corrosion characteristics. These features make SSR widely used in military science, chemical industry as well as various industrial and civil electric control devices.

    Solid state relay (SSR) is simple but widely used in the automation fields. Thus, it is not complex to wire a solid state relay. In this vedio, ATO takes a 40 Amp SSR (DC - AC) for example to show the wiring of a SSR and then switch on/off a motor with this SSR.

    Existing reviews of Solid state relay SSR-40DA, 40A 3-32V DC to AC
    This solid state relay works well.
    Bought a 40A solid state relay, DC to AC. After I received it, I connected this SSR to a motor for a test. The SSR and the motor worked. Cool!
