If you made one please click on I MADE IT button and also post the photo of your finished Diy relay module in comment section. Features: 5V 2 channel relay … digital logic or a sensor. Then wire the circuit on a breadboard. i am new to the world of electronics and i am still learning i am confused what's he purpose of J1 and J2 in the circuit can anyone please explain? So, i went to a local store to buy one but there is no 5 volt or 6 volt relay module.But fortunately they have the relays , i bought so many(hope i can use like this situation in future :D) .then made one myself.Its cheap and easy , you can save a little bit money by making these Diy relay module . 2 years ago. We made the Diy relay module on a general purpose PCB. Previously we have built 4-channel Relay Driver Module , but this time we are building this relay module as Arduino Shield, so that you just have to fix it … Take a look the schematic diagram and PCB layouts.Then wire the circuit on a breadboard.Double check the schematics diagrams and Breadboard wiring for any wrong connection. PCB LAYOUT INSTANT QUOTE. This is my second home automation project using the ESP8266 (NodeMCU). with relay . Before we proceed with the circuit to drive the relay we have to consider two important parameter of the relay. Established in the year 2017 at Navi Mumbai, Maharashtra, we “Embielectrotech” are a Sole Proprietorship based firm, engaged as the foremost Manufacturer of Relay Module, Sanitary Napkin Incinerator Controller, and many more.Our products are high in demand due to their premium quality, seamless finish, different patterns and affordable prices. Don't skip this step, it is necessary to avoid mistakes when soldering into a PCB and to check that it works. I made a single channel but you can make more on a same PCB.for multiple channel like 2 or more , make copies of the same circuit in a single PCB.So lets start making guys....!!!! J1 is the gates of the relay and J2 is for the power and signal. Now we have all the parts to make a Diy relay module. We successfully made our Diy relay module. PCB Power Relay Application Examples Relay Module for controlling 230V Power supply by using 5V signal with Proteus Simulation and PCB Design and making of the PCB with the same circuit. Relays are most commonly used switching device in electronics. " Relay module with 16/8/4 electromechanical relays." Relays are frequently used in our electronics applications specially when we need to drive high loads from microcontroller circuits. Relays mainly used for more than 3A load switch, and equipped in household appliances, such as refrigerators, washing machines, and AV device, as well as various FA equipment, industrial equipment, and household equipment. Then, I am soldering the NPN Transistor. carefull for wrong connections. Screw terminals(3 pols , 2 nos)6. Well, if you feel the need of having a simple relay module, with just the basic components, you are at the right place. In this example, we will connect the relay module with Arduino in the normally open state. HI! This figure shows an example of a hinged relay. FritzingGENERAL TOOLS:1. Question Can you throw some light on snubber circuit. Can you tell me how to go about snubber circuit or point me in right direction?Thank you! PCB Design-----So, this is how my 10x10 PCB looks like. Some will know, some won't, always worth adding in the extra few lines of explanation.. :). Step1: PCB Power Relay Diagram Great, I think everyone (who does electronics) should have build this at least once to learn. The products line-up includes relays that have enhanced insulation distance between coil contacts. Can I use 6v realy as 5v actually I want oprtate 12v lock using raspberry pi 3 what should I do......? Now we have all the parts to make a Diy relay module. don't skip this step , it is necessary to avoid mistakes when soldering into a PCB and check if it is works. The power relays for the board have suitable structures according to applications, and are generally composed of a plurality of components as shown in the following figure. Now we need to make the circuit on a General purpose pcb or custom pcb. Arduino Control Relay Module Bluetooth & IR 2 Layers PCB 100 x 100 mm FR-4, 1.6 mm, 1, HASL with lead, Green Solder Mask, White silkscreen In this Arduino project, I have explained how to control light, fan, and other home appliances from smartphone Bluetooth and IR remote using Many thanks to JLCPCB for high-quality PCB, and EasyEDA web software for making the schematic.. At the same time you can use this relay module like a ordinary relay module. Soldering iorn.2. After all parts you collected lets go ahead to the next step. I really recommend the Custom PCB,because the custom PCB is more clean and professional and less chance to short circuit. PCB. Take a look the schematic diagram and PCB layouts. Share it with us! great instructable,thank you for sharing..... About: Like to learn and do electronics and hardware stuffs, How to Make a IR Proximity Sensor at Home, CheApR - Open Source Augmented Reality Smart Glasses, "High-Fivey" the Cardboard Micro:bit Robot. Now we need to collect some parts that we needed to make the Diy relay module.NOTE : 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:HARDWARE:1. BC548 transistor.3. The switch may have any number of contacts in multiple contact forms, such as make contacts, break contacts, or combinations thereof.. The extra components apart from the relay are there since it would not be possible to drive the relay directly from the pins of a microcontroller. Yes, I am talking base bias to drive most any relay. After etch the PCB . Your Virtual Design Team. Reply Hi, This project works fine for me when I used BC558 PNP transistor, but when I plug a NPN transistor like this one used in this project: the LED didn't blinking !! With base (Relay-pluggable)" 1 Change over." Next we need to test the circuit diagram of the relay module on a breadboard. I just stated such a setup incase you don't have enough sing or source current capability from any microcontroller for such a driver setup. Good post and project. Relay Module; LED; Circuit Diagram and Explanation. There are a wide variety of industries that use power relays that can directly switch loads such as motors, lamps, and heaters. How to use a Relay. These power relays also retain excellent performance in contact volume and contact pressure. Hi guys how are you ?I hope you are fine !Are you looking for making a relay board yourself , then your in right place.today i will show you how to make a Diy relay modulethat can be used any purpose . Machine tools, molders, welders, mounters, and other industrial robots, Programmable controllers, temperature controllers, timers, and various I/O devices. I have explained this smart relay module circuit in the tutorial video of this home automation project.
