Solid state relays serve a wide range of industrial applications, using electronic components to switch a circuit on or off, ideal for applications requiring many contact closures and extended life. AD-70S2 series socket-mount relays are shock and vibration resistant; immune to humidity, salt spray and dirt; available in contact ratings up to 4A.
A solid state relay switch is a control relay with isolated input and output, whose functions are achieved by means of electronic components without the use of moving parts such as those found in electromechanical relays. These electronic relays are ideal for applications with many contact closures since solid state relay switches offer a greatly extended life compared to electromechanical relays.
Solid state relays (SSR) are similar to electromechanical relays, in that both use a control circuit and a separate circuit for switching the load. When voltage is applied to the input of the SSR, the relay switch is energized by a light emitting diode. The light from the diode is beamed into a light sensitive semiconductor which, in the case of zero voltage crossover control relays, conditions the control circuit to turn on the output of the solid state relay switch at the next zero voltage crossover.
