2 posts in this topic

hello gurus, Currently, I want to convert a fast switchig 120Vac signal to 24VDC signal. I am thinking of using optoisolators IAC. http://www.opto22.com/documents/0448_Std_D..._data_sheet.pdf But what should i do to put things together, any resistor and capacitor in the input ? Hope to hear from someone. thank you. Johnny

Use a simple solid state relay rated for the application. Crydom is a pretty popular name but I've been buying Continentals lately. Look in a Mouser catalog (www.mouser.com) or Digi-Key. The packaged solution tends to be a lot less trouble than building your own.
