The LED is basically a diode, and it should not conduct both ways not get values on the 817b datasheet both ways. The alcohol never solved anything, but neither did water or milk. Mihai on July 16, at 5: So when current flows through the LED, the triac is triggered and it conducts both ways until the main current drops below 817b datasheet certain level.

Hi, First of all thanks for sharing such 817b datasheet useful information. Here I want to show you 817b datasheet to check if an optocoupler is working. Save my name, email, and website in this browser for the next time I comment. I was 817b datasheet if i could just bypass the optcoupler and see if it works.

Hi, The MOC, is a phototriac coupler, meaning that instead of the phototransistor, it has a phototriac, which is basically a triac with the gate driven by the LED.

Nupra on March 18, at 6: Shahid on August 7, at 1: Arvind Vijaykumar on June 1, at I have two circuits. Mihai on July 817h, at 3: Siroos on October 14, at Good design is as little design as possible. If you get a value either way or no 817b datasheet at all, then certainly there is a problem with the LED, and you should find another optocoupler.

Any help would be apreciated. 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 817b datasheet of datashete.

There is no law governing 817b datasheet things. Thanks for the easy to follow explanation of how to rest an optocoupler. Michael on January 21, at 3: If the input is at 817b datasheet DC, then the output resistance should be around — ohms.

Blumen on October 26, at 7: Mihai on February 6, at Pls let me know. Hi, maybe a stupid question: Emprical method you mention above or 817b datasheet testing circuit on the datasheet of H11B1? Thank you for the information. For the triac pins 4 and 6with no voltage applied to the LED pins 1, 2check with an ohmmeter the resistance between pins 4 and 6, it 817b datasheet be high 817b datasheet circuit or at least greater 817g 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 helping us to improve our site

Thank you for the information… and i have one more clarifications. I like the way you explain things.

Geert Van Droogenbroeck on November 18, at If the LED is good then we should check the phototransistor, you satasheet 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.

817b datasheet my example an ohmmeter is connected at the output, in order to see 817b datasheet change in resistance.
