The Basics of Optocoupler Relay

We have all heard of the term relay in our life at one point or another. So, what is a relay? What is it used for? What are its types? In this article, we will get to know about all of the above questions. But, more specifically about the optocoupler relay?

So what is an Optocoupler Relay? A relay operating on the principle of opto-isolation, i.e. there is no direct or hardwire connection between the controller and the relay. And because there is no hardwire, the controller will remain protected against the high voltages that might harm the controller.

Now, coming to the actual optocoupler relay, let’s get started with the parts used in an optocoupler relay.
