How Does a Solid State Relay Work?
Answer
Solid state relay uses opto-coupling to provide complete electrical isolation between its low power input circuit and its high power output circuit. When the output switch is 'open' it has a nearly infinite resistance and a very low resistance when 'closed' .It can also be used to switch either AC or DC currents. Devices that are used in the control of high voltage or high power equipment need to have good electrical insulation between their high voltage output and low voltage input. Relying on a layer of silicon a few atoms thick to provide the required insulation is not really an option in such conditions.
