Description

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.

For more details about this circuit and design yourself, check out: 4-channel relay driver
