To design this relay driver circuit, we've got selected the online eda device called easyeda. We've formerly used easyeda in many instances and determined it very handy to apply as compared to different pcb fabricators. Take a look at right here our all the pcb initiatives. After designing the pcb, we are able to order the pcb samples via their low fee pcb fabrication offerings. In addition they provide factor sourcing provider wherein they've a massive stock of digital additives and users can order their required additives along side the pcb order. On this 4-channel relay motive force circuit we've used an optocoupler to trigger the npn transistor which similarly drives the relay. And optocoupler could be precipitated by way of the active low signal. Here we have used 12v 10amp relay in this pcb board, you may also use 5v relays.
While designing your circuits and pcbs, you may additionally make your circuit and pcb designs public in order that other users can copy or edit them and may take advantage from there, we've also made our entire circuit and pcb layouts public for this relay motive force module, take a look at the beneath link:. In this venture, we will make a 4-channel relay driver circuit for relay based packages. In this circuit, we've got designed an remoted pcb for 4 relays. With the aid of the usage of this relay board, we will function four ac home equipment at a time. We've got placed a three pin screw terminal blocks (nc, nuteral, no) for connecting appliances. Right here we have provided pcb format, circuit diagram and gerber documents, so you can build or immediately order this relay driver module.
