I don't if you use a HCPL-3700. It's rated 5 to 240V ac/dc sensing voltage so no problemPapabravo said:I'd be really careful about an opto on 240VAC mains. Would you care to compute the power disipated in the resistive divider or in the LED stage of the optoisolator. I think you will be amazed at how the required LED current wil fry the resistors.
Absolutely, we still don't know what anishkjohn want to do with his PDA.Papabravo said:Tell us again, are you interested in the voltage or the frequency of the 240VAC mains?
