I have a FMD 88 and my cabinet is getting a little hot in the summer. I think having the PLC turn on a fan after set point would be neat.
I'm out of digital outputs though. I am wondering if I can write a ~3V signal to a small cpu fan. Digikey has fans that run down around 0.1 Watts. If this is to much power could I maybe toggle a transistor?
I couldn't find anything in the manual on the current draw for the two D/A outputs.
Thanks for any help!
