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 June 10, at 817q You helped me understand how to use a tester on a optocoupler Thanks. I was wondering if i could just bypass the optcoupler and see if it works.

Better check the datasheet for a test circuit. I appriciate… I tried that emprical method ddatasheet H11B1 optocoupler. Thank you for the information. Mihai on March 6, at 2: Sarfaraz on November 8, at 9: Blumen on October 26, at 7: When Firefox stops working, you fire up Chrome.

Your email address will not be published. I guess, it should work mostly the same as a normal triac. Thanks for the easy to follow explanation of how to rest an optocoupler.

Thank you for the information… and i have one more clarifications. The nice thing about standards is dwtasheet you have so many to choose from. Here I want to show you how to check if an optocoupler is working. Viliam on September 7, at 1: Hi, maybe a stupid question: Geert Van Droogenbroeck on November 18, at Mihai on July 15, at 8: Please correct the pin numbers in image.

Learn how your comment data is processed. An optocoupler or optoisolatoris a device that contains a light-emitting diode LED and a photosensor photodetector, such as a photoresistor, a photodiode, a phototransistor, …etc. I hope it helps. Arvind Vijaykumar on June 1, at How the optocoupler Type SFH acts when the positive line is open. This site uses Akismet to reduce spam.

Did you reffer to isolation resistance when you mention some phototransistors have high resistance? The alcohol never solved anything, but neither did water or milk. The question is which one is the 817w testing method?

Mihai on March 18, at But what i want to mention is there is a different testing circuit on the datasheet of H11B1. Sanu sebastian on August 19, at Michael on January 21, at 3: Sunil on March 3, at 3: Ado on November 14, at 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.

If i give the input of V DC what will be the response of this optocoupler…. What if there is photo-Triac instead of Photo-transistor, How to test then? Mihai on July 19, at 3: In my example an ohmmeter is connected at the output, in order to see the change in resistance. Any help would be apreciated. Pls let me know. I was referring to the junction resistance.

Hi, First of all thanks for sharing such an useful information. Hi, Both methods are correct. If the input is at 2V DC, then the output resistance should be around — ohms.

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. Mihai datssheet February 2, at 5:
