4 Channel 5v Relay Module Circuit Diagram

Now we need to collect some parts that we needed to make the diy relay module.

4 channel 5v relay module circuit diagram. By using this relay board we can operate 4 ac appliances at a time. It is equiped with high current relays that work under ac250v 10a or dc30v 10a. Vcc connect 5v to this pin. Here we have used 6v relay module.

In this arduino relay control circuit we have used arduino to control the relay. Before we proceed with the circuit to drive the relay we have to consider two important parameter of the relay. Is used to power the opto couplers. Let us learn how to use one in our circuits based on the requirement of our project.

The 1 channel relay module could be considered like a series switches. In this project we will make a 4 channel relay driver module circuit for relay based applications. This is a 5v 4 channel relay interface board and each channel needs a 15 20ma driver current. Relays are most commonly used switching device in electronics.

Relay driver circuit explanation. Most relay modules whether 5v or 12v will come with the aforementioned connection and hence all you need is to give power supply to the relay module i e. 3v relay 12v relay 1 channel relay module 4 channel relay module. It can be used to control various appliances and equipment with large current.

5v and gnd and connect the control signal from arduino to control. In this circuit we have designed an isolated pcb for 4 relays. It can be used to control various appliances and equipment with large current. Here to turn on the relay with arduino we just need to make that arduino pin high a0 in our case where relay module is connected.

1 normally open no 1 normally closed nc and 1 common pins com. Circuit diagram and working. We have put a three pin screw terminal blocks nc nuteral no for connecting appliances. It is equipped with highcurrent relays that work under ac250v 10a or dc30v 10a.

4 channel 5v optical isolated relay module this is a low level 5v 4 channel relay interface board and each channel needs a 15 20ma driver current. Relay will turn on when this input goes below about 2 0v. Below given is relay driver circuit to build your own relay module. This instructable is for connecting your arduino to a 2 channel relay module and using your sketch to control the switches i bought the 2 relay module on ebay for 9 50 to drive a couple of 240v parts a vacuum cleaner and a rotary engraving tool.

In this 4 channel relay driver circuit we have used an optocoupler whic his triggered by active low signal to trigger the npn transistor which further drives the relay. Most of the parts was lying around my home i used to save little more here the list of all the parts you needed to do this project. Here we have used 12v 10amp relay in this pcb board but you can also use 5v relays. How to use a relay.
