What if there is photo-Triac instead of Photo-transistor, How to test then?

There pjotocoupler no law governing all things. Some features may not work properly. The alcohol never solved anything, but neither did water or milk. Thank you for your feedback. I have two circuits.

In my example an ohmmeter is connected at the output, in order to see the change in resistance.

It depends on the 2nd circuit you are supplying the voltage on collector of the optocoupler, optocoupler will never transfer the voltages photocokpler circuit1 to circuit2, it decreases resistance between your supplied voltages at collector and emitter on the input of circuit2.

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.

Please enter a message. Did you reffer to isolation resistance when you mention some phototransistors have high resistance? Please correct the pin numbers in image.

For response time or frequency response data, check the datasheet. Emprical method you mention above or the testing circuit on the datasheet of H11B1? Mihai on July 16, at 5: Mihai on Phhotocoupler 27, at By clicking the accept button below, you agree to the following terms.

I was wondering if i could just bypass the optcoupler and see if it works. The nice thing about standards is that you have so many to choose from. The optocoupler is FL C F, should i just join the emittor and collector pins? I hope it helps. The Manufacturers reserve the right to change this Information at any time without notice.
