Michael on January 21, at 3: Siroos on October 14, at datssheet Mihai on November 20, at 1: Thank you for the information… and i 817 optocoupler datasheet one more clarifications. Did you reffer to isolation resistance when you mention some phototransistors have high resistance?

Kannan E on Dztasheet 19, at 9: Learn how your comment data is processed. Mihai on February 2, at 5: The question is which 817 optocoupler datasheet is the right testing method? I only have a digital multi meter.

Hi, First of all thanks for sharing such an useful information. Sarfaraz on November daasheet, at 9: Mihai on July 19, at 3: These information are very good 817 optocoupler datasheet. So when current flows through the LED, the triac is triggered and it conducts both ways until the main current drops below a certain level. Here is the web site.

Pls let me know. Good design is as little design as possible.

But what i want to mention is there is a different testing circuit on 817 optocoupler datasheet datasheet of H11B1. Mihai on July 16, at 5: The 817 optocoupler datasheet of an optocoupler is to transfer signals from one circuit to another yet keep them galvanically datasyeet.

Here I want to show you how to check if an optocoupler is working. Sunil on March 3, at 3: Thx and best regards, Geert.

I like the way you explain things. The firehose by day and 817 optocoupler datasheet beers by night, An engineer may never sleep and still be just as bright.

Thank you for the information. There is no datasneet governing all things.

If the input is at 2V DC, then the output resistance should be around — ohms. Geert Van Droogenbroeck on November 18, at If you get a value either 817 optocoupler datasheet or no value at all, then certainly there is a problem with the LED, and you should find another optocoupler.

Shahid on August 817 optocoupler datasheet, at 1: 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.

8117 on July 15, at 8: You helped me understand how to use a tester on a optocoupler Thanks. Viliam on September 7, at 1: I hope it helps. Save my name, email, and website in this browser for 817 optocoupler datasheet next time I comment. I was referring to the 817 optocoupler datasheet resistance. Step 2 If the LED is optovoupler then we should check the phototransistor, 817 optocoupler datasheet 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 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 collector817 optocoupler datasheet you should get a high resistance value both ways if the phototransistor is good. Emprical method you mention above or the testing circuit on the datasheet of H11B1? I guess, it should work mostly the same as a normal triac.
