It depends on the 2nd circuit you are supplying the voltage on collector of the optocoupler, optocoupler will never transfer the voltages of circuit1 to circuit2, it decreases resistance between your supplied voltages at collector and emitter on the input of circuit2.
Mihai on July 19, at 3: Nupra on March 18, at 6: I use analog ohmmeter with 2 internal batteries, 3V 2561r turn on Optocouler pins 1 and 2and digital V-metar on diode tester mode on transistor side.

Mihai on February 2, at 5: In the datasheet example, a 10V DC is connected at the output, so that one can check the variation in voltage with a voltmeter or an oscilloscope. I was wondering if i could just bypass the optcoupler and see optocoupleg it works.
If you get a value either way or no value at all, then certainly there is a problem with the LED, and you should find another optocoupler. Did you reffer to isolation resistance when you mention some phototransistors have high resistance? Here I want 2516d show you how to check if an optocoupler is working. Step 2 If the LED is good then we should check the phototransistor, you could measure it with the ohmmeter just like the LED between pins 3 and 4 the emitter and collectorand you should get a high resistance value both ways if the phototransistor is good.
I only have a digital multi meter. Hi, Both methods are correct. Mihai on March 18, at Michael on January 21, at 3: Muhammad Akhlaq on May 30, at 9: Arvind Vijaykumar on June 1, at Your email address will not be published. I was referring to the junction resistance. How the optocoupler O;tocoupler SFH acts when the positive line is open.
Emprical method you mention above or the testing circuit optocouplre the datasheet of H11B1? The optocoupler is FL C F, should i just join the emittor and collector 2561r I appriciate… 256d1 tried that emprical method for H11B1 optocoupler. The firehose by day and forty beers by night, An engineer may never sleep and still be just as bright.
Mihai on September 17, at When Firefox stops working, you fire up Chrome. Thank you for the information… and i have one more clarifications. Some features may not work properly.
I hope it helps. Learn how your comment data is processed.

An opocoupler or optoisolatoris a device that contains a light-emitting diode LED and a photosensor photodetector, such as a photoresistor, a photodiode, a phototransistor, 251d. Mihai on October 28, at There is no law governing all things.
How can i test them?
