Hi all
I need to interface a PIC Input to a Volt Free Contact in a building. Would it be wise to use an opto-isolator? I Have 24v available on my board too, and I was considering using that through the Opto-isolator's led, as it is possible there may be some distance to the VFC, and I was worried about picking up noise, and also the possible voltage drop..
Thanks
John
