Hello
I am in the process of designing a PCB that incorporates a microcontroller, LEDs, capacitive sensors and relays to control light in my smart car. I have taken this picture as my reference.I have the little stuff worked out and have it prototyped and working, but I want some outside input on the relays on the board.
The relays are S2-L2-24v 4A NAIS relays. They are triggered by the microcontroller when it receives a certain input.(I take this datasheet as my reference: http://html.alldatasheet.com/html-pdf/1 ... ELAYS.html)
I want to make sure that I have adequate trace widths to support the relays when an auxiliary component is triggered. Right now I plan to use 1 oz copper for the board when I have it printed (trace width is 150 mil on the relays and power). I have attached the PCB design to this post.
Each individual relay would have a max of 1A /30V on it, and all power lines on the board are fuse protected. In all reality, it is likely that only one relay would be on at a time.
I am new to incorporating these things in to a PCB, so I may be approaching this completely wrong. Am I using the right relays? So any suggestion will greatly be appreciated!
