Shield with optocouplers


I’m looking for a shield which has let’s say 4 opto-couplers … anyone knows it it exists ?

Cheers Willem.

Hi Willem,

Check - - and maybe this site is interesting - -

Hi Willem, I don't know of a specific shield which has a bunch of OK's on it, but here's a non-shield design that may help you in designing one - in this case it daisy-chains all OK's (to split an already opto-coupled input), but it's a decent starting point for a schematic and layout:


Hi, What do you want the optocouplers to DO??

  • Input signal isolation?
  • Output circuit isolation?
  • Signal modification?
