Hey everybody
I'm trying to design and build a lighting controller with a pc output interface and a custom desgned relay board. Basically, i want to use this board along with an external 12vdc source to power relays which will power on 120vac outelts. These outlets will have lights plugged into them, and i'll use of a few different software options to drive the output board to program lighting sequences.
Here is the custom relay board i would like to make:
At the top is a screw terminal connector. The first terminal (all the way to the right in the picture) is from the 12v source and is supplied constant to the relays and the LEDs on the right (which are just test indicators for the relays) Then the next 4 terminals on the block are the grounds for each "channel" of lighting. The output board i picked pulses ground rather than voltage so thats why i did it like this. Each ground is connected between one relay and one LED in parallel. So connected to the top terminal will be the 12 volt source and the ground for each seperate channel of light. Then the bottom connector has the 120vac source all the way to the left and then to the right of that it has the 4 seperate "switched" wires the will get connected to the outlets for the output lighting. Also if you can't tell in the middle of the board those are just the holes for the relays which can be seen here
Okay so my question is: will it work? I've tested one "control" circuit without the 120VAC ouput and it worked.
I'm confident it will work I'm more concerned with the indicator LEDs how they're wired and then the actual layout of the traces and components on the board. I think i convered the whole circuit, if you need help deciphering anything i did just let me know. Thanks in advance for any help
