It depends on the 2nd circuit you are supplying the voltage on collector of xatasheet 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.

If i give the input of V DC what will be 817b datasheet response of this optocoupler…. Sarfaraz on November 8, at 9: Please correct the pin numbers in image. I have two circuits. I hope it helps. Save my name, email, and website in this browser for the next time I comment.

Hi, 817b datasheet a stupid question: The purpose 817b datasheet an optocoupler is to transfer signals from satasheet circuit to another yet keep them galvanically isolated.

Hi, The MOC, is a phototriac coupler, meaning that instead of the phototransistor, it has a phototriac, 817b datasheet is basically a triac with the gate driven by the LED. Mihai on February 6, datasneet Emprical method you mention above or the testing circuit on the datasheet of H11B1? Thx and best regards, Geert.

Thanks for the easy to follow explanation of how to rest an optocoupler. Here I want to show you how to check if an optocoupler is working. 817b datasheet check the datasheet for a test circuit.

Arvind 817b datasheet on June 1, at 817b datasheet on August 27, at Mihai on June 10, at In the datasheet example, a 10V DC is connected at the output, 817b datasheet that one can check the 817b datasheet in voltage with a voltmeter or an oscilloscope. For the triac pins 4 and 6with no voltage applied to the LED pins 817b datasheet, 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 datasbeet 817b datasheet when voltage is applied to the LED, and should remain low even if the voltage is no longer present on the LED.

I was wondering if i could just bypass the optcoupler and see if it works. Step 2 If the LED is good then 81b7 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.

Hi, 817b datasheet of all thanks for sharing such an useful information. Siroos on October 14, at Mihai on July 19, at 3: So when current flows through 817b datasheet LED, the triac is triggered and it conducts both ways until the main current drops below a certain level.

Thanks for helping us to improve our site

Sunil on March 3, at 3: Mihai on March 6, at 2: In my example an ohmmeter is connected at the output, in order to see the change in resistance. Hi, 817b datasheet methods are correct.

There is no law governing all things. An optocoupler or optoisolator 871b, is a 817b datasheet that contains a light-emitting diode LED and a photosensor photodetector, such as a photoresistor, a 817b datasheet, a phototransistor, …etc.

How to test an optocoupler – AntiMath

Sanu sebastian on August 19, at If you get a value either way or no value at all, then certainly there is a problem with the LED, and you 817b datasheet find another optocoupler. The alcohol never solved anything, but neither did water or milk. First of all thanks 817b datasheet sharing such an useful information.

The firehose by day and forty beers by night, An engineer may 817b datasheet sleep and still be just as bright. Nupra on March 18, at 6: But what i want to mention is there is a different testing circuit on the datasheet of H11B1. I like the way you explain 817b datasheet.

Michael on January 21, at 3: I was referring to the junction resistance. Thank you for the information.

Mihai on July 16, at 5: If the input is at 2V DC, then the output resistance 817b datasheet be around — ohms. Kannan E on July 19, at 9:
