4 Channel 5v Relay Module Circuit Diagram

How to use a relay.
4 channel 5v relay module circuit diagram. Let us learn how to use one in our circuits based on the requirement of our project. Relay driver circuit explanation. Below given is relay driver circuit to build your own relay module. Relay will turn on when this input goes below about 2 0v.
Is used to power the opto couplers. In this circuit we have designed an isolated pcb for 4 relays. It is equipped with highcurrent relays that work under ac250v 10a or dc30v 10a. Circuit diagram and working.
Relays are most commonly used switching device in electronics. 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. Vcc connect 5v to this pin.
By using this relay board we can operate 4 ac appliances at a time. Now we need to collect some parts that we needed to make the diy relay module. 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. It is equiped with high current relays that work under ac250v 10a or dc30v 10a.
It can be used to control various appliances and equipment with large current. Here we have used 12v 10amp relay in this pcb board but you can also use 5v relays. It can be used to control various appliances and equipment with large current. 5 volt relay i used 6 volt because i need 6 volt relay 2.
Although the circuit diagram explains the detailed connections practically we didn t need to make all the connections. The 1 channel relay module could be considered like a series switches. 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. Arduino 2 channel relay.
3v relay 12v relay 1 channel relay module 4 channel relay module. We have put a three pin screw terminal blocks nc nuteral no for connecting appliances. 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. In this project we will make a 4 channel relay driver module circuit for relay based applications.
In this arduino relay control circuit we have used arduino to control the relay. 1 normally open no 1 normally closed nc and 1 common pins com. 5v and gnd and connect the control signal from arduino to control. This is a 5v 4 channel relay interface board and each channel needs a 15 20ma driver current.
