4-Channel Relay Driver Module

In this project, we will make a **4-Channel Relay Driver Module Circuit** for relay based applications. In this circuit, we have designed an isolated PCB for 4 relays. By using this **Relay Board**, we can operate 4 AC appliances at a time. We have put a three pin screw terminal blocks (NC, Nuteral, NO) for connecting appliances. Below are the circuit diagram and PCB layout designs of the relay driver.
