Solid State Relay can be used as an alternative solution of using electromagnetic relay. Where it can provice fast switching speed, which is about less than equals to 1ms. No mechanical moveable parts, thus it will provide you more longevity then others. Also you don't need to provide any extra power from your controller. Solid state relay can be operated with wide range of input voltage ranges from 4.5V to 20V. And the load voltage and load current is multiple times greader than the electromagnetic relay. This relay module is fully isolated from the AC part using opto isolation techinique.
