DIY 4 Head Doser 0-10V Port

[lbrdsoxfan]

Hi folks, I know this is a old thread, but I figure they key to this is to use a 0-10v output port to send a signal to the control board to cycle the pump on/off.

I currently have a launch and xp8, and most of the other components around already. I'm trying to see what else I need to make this happen.

Thx!!

Question for those using the red relay module boards... are you able to wire the 0-10v analog signal directly to the digital optocoupler trigger on the relay board? I see HIGH is digital 2.5v-5v

ChatGPT suggested I put a transistor between them. Simple enough and I have spare parts to do it, just wondering

For the parts I have on hand, I was thinking of this for each input

I think AI has lead me horribly astray here, sorry I cannot edit my own post to correct it.
