I'm trying to decide on a resistor value to use with some cpc1017n opto relays.
The datasheet is here: http://www.ixysic.com/home/pdfs.nsf/www/CPC1017N.pdf/$file/CPC1017N.pdf
It specs it at 50ma but I don't see a voltage.
Some eBay listings give the voltage as 1.4 but that seems a bit out of the norm to me.
I'm using 12v for the input and if I use the 50ma and the 1.4v that gives me a 220 ohm, 1 watt resistor.
Does that sound like a safe bet?
