How to use a relay.
This is a 12v 16 channel relay interface board be able to control various appliances and other equipments with large current.
There are two important parameters of relay first is the trigger voltage this is the voltage required to turn on the relay that is to change the contact from common nc to common no.
Before we proceed with the circuit to drive the relay we have to consider two important parameter of the relay.
Let us learn how to use one in our circuits based on the requirement of our project.
