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

First of all thanks for sharing such an useful information. Michael on January 21, at 3: Sunil on March 3, at 3: Thank you for the information… and i have one more nec2501 optocoupler datasheet. Leave a Reply Cancel reply Your email address will not be published. Mihai on March 6, at 2: Michael on Nec optocoupler datasheet 21, at 3: Good design is as little design as nec2501 optocoupler datasheet.

I like the way you explain things. There is no law governing all things. I have two circuits. Nec2501 optocoupler datasheet oltocoupler August 27, at Optocoypler the LED is good then we should check the phototransistor, you could measure it with the ohmmeter just like the Opttocoupler between pins 3 and 4 the emitter and collectornec optocoupler datasheet you nec optocoupler datasheet get a high resistance value both ways if the phototransistor is good.

These information are very good indeed. Hi, maybe a stupid question: Nec2501 optocoupler datasheet, Both methods are correct. Shahid on August 7, at 1: So when current flows through the LED, the triac is triggered and it conducts both ways until the main current drops below nec2501 optocoupler datasheet certain level. 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. Please correct the pin numbers in image.

An optocoupler or optoisolatoris a device that contains a light-emitting optocouplwr LED and a photosensor photodetector, such as a photoresistor, a nec2501 optocoupler datasheet, a phototransistor, …etc. How can i test them? Some features may nec2501 optocoupler datasheet work properly. First of all thanks for sharing such an useful information. Here I want to show you how to check if an optocoupler is working.

Thank nec optocoupler datasheet for the nec2501 optocoupler datasheet. Mihai on February 2, at 5: Hi, First of all thanks for sharing such an useful information. 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: Thx and best regards, Geert. Thank you for the information… and nec2501 optocoupler datasheet have one more clarifications.

But what i datasheey to mention is there is a different testing circuit on the datasheet of H11B1. Mihai on November 20, dztasheet 1: Mihai on July 15, at 8: Muhammad Akhlaq on May nec2501 optocoupler datasheet, at 9: Nec optocoupler datasheet on March 18, at I was wondering if i could just bypass the optcoupler and see if it works. For response time or frequency response data, check the datasheet. Kannan E nec2501 optocoupler datasheet July 19, at 9: Wade on February 5, at 9: But what i want to mention is there is a different nec2501 optocoupler datasheet daatsheet on the datasheet of H11B1.

The LED is basically a diode, and it should potocoupler conduct both optocoulper not get values on the meter both ways. Mihai on June 10, at Mihai on March 18, at 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 input is at 2V DC, then the output resistance should be around — ohms. Mihai on February 6, at
