The LED is basically a diode, and it should not conduct both ways not get values on the meter both ways.

Arvind Vijaykumar on June 1, at 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.

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

I guess, it should work mostly the same as a normal triac. Thank you for the information… and i have one more clarifications. Mihai on September 17, at The alcohol never solved anything, but neither did water or milk.

Sanu sebastian on August 19, at Hi, maybe a stupid question: But what i want to mention is there is a different testing circuit on the datasheet of H11B1.

Muhammad Akhlaq on Potocoupler 30, at 9: I like the way you explain things. The firehose by day and forty beers by night, An engineer may never sleep and still be just as bright. Mohamed on October 9, at 9: Sarfaraz on November 8, at 9: Some features may not work properly. If the input is at 2V DC, then the output resistance should be around — ohms.

I appriciate… I tried that emprical method for H11B1 optocoupler.

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.

How can i test them? For the triac pins 4 and 6with no voltage applied ootocoupler the LED pins 1, 2check with an ohmmeter the resistance between pins 4 and 6, it should be high open circuit or at least greater than 1 megohm both ways, and this resistance should go down lower than ohms when voltage is applied to the LED, and should remain low even if the voltage is no longer present on the LED.


Thanks for the easy to follow explanation of how to rest an optocoupler.

Thx and best regards, Geert. Wade on February 5, at 9: Michael on January 21, at 3: Mihai on February 6, at Mihai on October 28, at The purpose of an optocoupler is to transfer signals from one circuit to another yet optocouple them galvanically isolated.

The optocoupler is FL C F, should i just join the emittor and collector pins? With no voltage applied to the LED pins 1 and 2and with an open base pin 6there should be a high resistance between pins 5 and 4.

Nupra on March 18, at 6: Mihai on March 6, at 2: I was referring to the junction resistance. Mihai on August 27, at The nice thing about standards is that you have so many to choose from. Mihai on July 15, at 8: The question is which one is the right testing method?

I have two circuits. Your email address will not be published.
