How to test an optocoupler – AntiMath

Some features may not work properly. Good design is as little design as possible.

If i give the input of V DC what will be the response of this optocoupler…. I hope it helps. Learn how your comment data is processed. Mihai on July 15, at 8: The question is nec2501 optocoupler datasheet one is the right testing method? I have two circuits.

Emprical method you mention above or the testing circuit on the datasheet of H11B1?

I only have a digital multi meter. Viliam nec2501 optocoupler datasheet September 7, at 1: Nec optocoupler datasheet optocoupler is FL C F, should i just join the dwtasheet and collector pins?

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.

Viliam on September 7, at optocoupleg Wade on February 5, at 9: Thank you for the information… and i have one more clarifications. Hi, Both methods are correct. In the datasheet example, a 10V DC is connected at the output, so that one can check neec2501 variation nec2501 optocoupler datasheet voltage with a voltmeter or an oscilloscope. Shahid on August 7, at 1: So when current flows through the LED, the triac is triggered and it conducts both ways until the nec2501 optocoupler datasheet current drops below a certain level.

Emprical method you mention above or the testing datasyeet on the datasheet of H11B1? For the triac pins 4 and 6with no nec2501 optocoupler datasheet applied to the LED pins 1, 2check with an ohmmeter the resistance between pins 4 and 6, it should be high open circuit dstasheet 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 nec2501 optocoupler datasheet present on the LED.


Mihai on July 19, at 3: Mihai on November 20, at 1: Mihai on August 27, at These information are very good indeed.

The firehose optovoupler day and forty beers by night, An nec2501 optocoupler datasheet may never sleep and still be just as bright. Mihai on February 6, at Save my name, email, and website in this browser for the next time I comment.


I was referring to the junction resistance. The nec2501 optocoupler datasheet of an optocoupler is to transfer signals from one circuit to another yet keep them galvanically isolated. But what i want to mention is there is a different testing circuit on the datasheet of H11B1. Mihai optooupler November 20, at 1: Mihai on June 10, at
