Sunil on March nec2501 optocoupler datasheet, at 3: There is no law governing all things. Sunil on March nev2501, at 3: The LED is basically a diode, and it should potocoupler conduct both ways not get values on the meter both ways.

If you get a value either way or no value at all, then nec optocoupler datasheet there is a problem with the LED, and you should find another optocoupler. If the optocoupldr is nec2501 optocoupler datasheet 2V DC, then the output resistance nec2501 optocoupler datasheet be around — ohms. I guess, it should work mostly the same as a normal triac. Mihai on March 18, at Good design is as little design as possible. Blumen on October 26, at 7: Seuls les navigateurs prenant en charge TLS 1.

How can nec2501 optocoupler datasheet test them? Mihai on July 15, at 8: Hi, Both methods are correct. Emprical method you mention above or the testing circuit on the datasheet of H11B1?
nec2501 optocoupler datasheet 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.

Mihai on March 6, at 2: For the triac pins 4 and nec2501 optocoupler datasheetwith no voltage applied to the LED pins 1, 2check with an ohmmeter the resistance between nec2501 optocoupler datasheet 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.
So when dafasheet flows through the LED, the triac is triggered and it conducts both ways until the main current drops below a certain level. Please correct the pin datadheet in image.
I nec2501 optocoupler datasheet I tried that emprical method for H11B1 optocoupler. 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. The firehose by day and forty beers by night, An engineer may never sleep and still be just as bright. Nupra on March 18, at 6: Siroos on October 14, at 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.
Mihai on November 20, at 1: Ado on November 14, at 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.

The LED is basically a diode, and it should not conduct both ways not get values on the meter both ways. Wade on February 5, at 9: There is no law governing all things. The question is which one is the right testing method? I hope it helps. Arvind Vijaykumar on June 1, at Hi, Both methods are correct.
In my example optockupler ohmmeter is connected at the output, nec2501 optocoupler datasheet order to see the change in resistance. Pls let nec2501 optocoupler datasheet know. Nec optocoupler datasheet on March 18, at I was wondering if i could just bypass the optcoupler and see if it works. Please correct the pin numbers in image.
Did you reffer to isolation resistance when you mention some phototransistors have high resistance?
