AD-70S2 Series Solid State Relay Switches

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.

Operational Overview:
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.

Solid state relays have advantages which electromechanical relays do not, such as:

Long life
Shock and vibration resistance
No generation of RFI, EMI
No contact bounce
Arcless switching
No acoustic noise
Zero voltage switching
IC compatibility
Immunity to humidity, salt spray and dirt
