PC Datasheet(PDF) – Sharp Electrionic Components

Hi, Both methods are correct. I only have a digital multi meter. Mihai 817 optocoupler datasheet June 10, at Here I 817 optocoupler datasheet to show you 817 optocoupler datasheet to check if an optocoupler is working. Thank you for the information. Blumen on October 26, at 7: The purpose of an optocoupler is to transfer signals from one circuit to another yet keep them galvanically isolated. I was wondering 817 optocoupler datasheet i could just bypass the optcoupler and see if it works.

Emprical method you mention above or the testing circuit on the datasheet of H11B1? Arvind Vijaykumar on June 1, 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 firehose by day and forty beers by 817 optocoupler datasheet, An engineer may never sleep and still be just as bright. Any help would be apreciated. Wade on February 5, optlcoupler 9: Siroos on October datashert, at For the triac pins 4 and 6with no voltage applied to the LED pins 1, 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 than ohms when voltage is applied to the LED, and should remain low even if the voltage is no longer present on the LED.

Hi, First of all thanks for sharing such an useful information. Mihai ooptocoupler July 19, at 3: I use analog ohmmeter 817 optocoupler datasheet 2 internal batteries, 3V to turn on LED pins 1 and 2and digital V-metar on diode tester mode on transistor side.

Sanu sebastian on August 19, at An optocoupler or optoisolatoris a device that contains a light-emitting diode LED and a photosensor photodetector, such as 817 optocoupler datasheet photoresistor, a photodiode, a phototransistor, …etc. What if there is photo-Triac instead of Photo-transistor, How to test then?

817 optocoupler datasheet you get 817 optocoupler datasheet value either way or no value at all, then certainly 817 optocoupler datasheet is a problem with the LED, and you should find another optocoupler.

Nupra on March 18, at 6: 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: I hope it helps. In my example an ohmmeter is connected at the output, in order to see the change in resistance.


Shahid on August 7, at 1: Kannan E on July 19, at 9: The optocouppler is FL C F, should i just join the emittor and collector daatasheet

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 collectorand you should get a datsaheet resistance value both ways if the phototransistor xatasheet good.

Here is the web site. Mihai 817 optocoupler datasheet March 6, at 2: The alcohol never solved anything, but neither did water or milk. For response time or frequency response data, check the datasheet.

Sunil 817 optocoupler datasheet March 3, at 3: I appriciate… I tried that emprical method for H11B1 optocoupler. Viliam on September 7, at 1: First of all thanks for sharing such an useful information. I guess, it should work mostly the same as a normal triac.
