Re: Powering Stir Plate Fans

Does it draw power from the power supply or from mains voltage? COM (relay) - +12V (PSU) NO (relay) - +12V (fan) GND (fan) - GND (PSU) I'm also seeing some pwm fans and wondering...is it possible to control those the same way I do with the driver for my peristaltic pumps with the l92n motor driver?...

Thanks for the response. Do you have a schematic for the wiring? Also what size resistor would you recommend? Thanks!
I used a TLP185 and a 1k resistor.
