I am a new poster and would greatly appreciate assistance on the correct hook-up of an optocoupler/optoisolator. I am working with a NTE3098 (spec sheet link below).
https://www.nteinc.com/specs/3000to3099/pdf/nte3098.pdf
My input source is 3.6v from DC Supply (or equivalent battery) to 100ohm, 1/4w resistor on the (+) side to the Anode and the (-) side to the Cathode. The output is to 100ohm, 1/4w resistor on the (+) side to the Collector and the (-) side to the Emitter terminating to the leads of a Multimeter set to read DC output. I’ve confirmed a good connection on all working components but the consistent DC output is “0” on the Multimeter.
My understanding is that a function (among others) of the optocoupler/optoisolator is to transfer 100% of the voltage and current from the LED side to the photo-sensor side with ground loop isolation in between.
My application is a simple DC circuit that feeds continuous low voltage and current to a second circuit with ground isolation between them so, I thought, this would be the ideal solution. I’ve now tried several NTE3045, NTE3041, NTE3098 in combinations of 100ohm, 360ohm and 1k resistors respectively with similar results. Only with the NTE3041 (6-pin) did I get a trace .48v output – but that was with the (+) side to the Base pin and the (-) side to the Collector pin.
I am a not a professional so I am obviously not hooking-up correctly and could use any help or advice that would solve this problem. Or, if you have a better suggestion for me to achieve my purpose it would be greatly appreciated.
