Hello. Welcome. And thank you for the click......
Little background: I’m good with code and plug and play hardware... and can do basic soldering... but my knowledge of electronic circuits and components I’m no good. I tried to search online for answers but I’m a little stuck.
I have been trying to figure out how to control relays with 24v DC coils from an esp32 or similar arduino.
What I’ve read so far is:
Use a mosfet connected to the arduino pin to switch a 24v power circuit that’s connected to the coil of the relay.
Use a 5v relay to control the 24v relay
I was actually hoping that there was a #3 option such as an easy to use premade breakout board or shield to send 24v signals from the arduino.
The idea behind all this being that industrial relays are usually not 5v coils but 24v coils. I want to be able to use all these 24v relays in my panels... and instead of using a 24v plc controller (which I don’t have) I wanted to control it with the arduino (since arduino is my jam!) Looking for an easy option, I know I there’s an easy way I just don’t know how.
