Unkown parts

ChrisP

This is kinda like throwing a message in the bottle into the ocean but I'm hoping I'll get lucky. Went on a parts spree to my favorite surplus supplier today and while sorting through the place for the parts I was after I ran across what was probably a dual channel opto isolator. So far it looks like thats it, both sides isolated from each other, 1-4 pins grouped 1,2 3,4 but its reading 11 meg across what would be the LED from either polarity.

The only markings on it are......

Yup I'm a scrounge and about to head off for destructive testing to see what I can come up with, after searching yahoo, Digikey, Mouser and Newark no hits on the number for an optoisolator. Was just wondering if there was another place to look up specs on this critter.

check with some of the industrial electronic/ plc sites/forums, sounds to me like you have an ac input opto

Destructive testing revealed its an AC input opto, you were right on the money. Also it looks like the output pinning is inverted. 8·neg 7·pos 6·pos·5 neg. So far I'm not even finding that configuration but still looking and thanks.

Thanks, so far I've found the pinning, and under the glass its revealed as packaged in Thailand. I can use it at this point, it would just be nice to have the full data sheet on it. The only thing I've come across that schematicaly matches it is a Vishay part but the packaging dimensions differ from that one.
