4 Channel 5v Relay Module Circuit Diagram

Circuit diagram and working.

4 channel 5v relay module circuit diagram. Before we proceed with the circuit to drive the relay we have to consider two important parameter of the relay. By using this relay board we can operate 4 ac appliances at a time. 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 arduino relay control circuit we have used arduino to control the relay. It is equiped with high current relays that work under ac250v 10a or dc30v 10a. 3v relay 12v relay 1 channel relay module 4 channel 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.

How to use a relay. Arduino 2 channel relay. Relay will turn on when this input goes below about 2 0v. 1 normally open no 1 normally closed nc and 1 common pins com.

Is used to power the opto couplers. Now we need to collect some parts that we needed to make the diy relay module. 5 volt relay i used 6 volt because i need 6 volt relay 2. 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.

This is a 5v 4 channel relay interface board and each channel needs a 15 20ma driver current. We have put a three pin screw terminal blocks nc nuteral no for connecting appliances. Vcc connect 5v to this pin. Here we have used 12v 10amp relay in this pcb board but you can also use 5v relays.

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. 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. 5v and gnd and connect the control signal from arduino to control. Relay driver circuit explanation.

Below given is relay driver circuit to build your own relay module. 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. It can be used to control various appliances and equipment with large current. Here we have used 6v relay module.

It is equipped with highcurrent relays that work under ac250v 10a or dc30v 10a. In this circuit we have designed an isolated pcb for 4 relays. In this project we will make a 4 channel relay driver module circuit for relay based applications. 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.
