Easy to use solid state relay module with 5V operation, no additional relay driving circuitry is required, can be triggered directly from logic level signals. Can switch up to 240 VAC at 2A current level. LED indication of ON relay is also given on the module board. SSR gives better performance with respect to traditional coil based relay as they are no mechanical parts inside, no chances of mechanical wear and tear. Long life relay with quite operation, no relay ticking sound.
