Mihai on July 16, at 5: Michael on January 21, at 3: Here I want to show you how to check if an optocoupler is working.

cosmo datasheet & applicatoin notes – Datasheet Archive

I like the way you explain things. Mihai on March 6, at 2: The LED is basically a diode, and it should not conduct both ways not get values on the meter both ways. So when current flows through the LED, the triac is triggered and it conducts both ways until the main cosmo110 drops below a certain level. Sunil on March 3, at 3: Arvind Vijaykumar on June 1, at Ado on November 14, at 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 high resistance value both ways if the phototransistor is good.

Hi, Both methods are correct.

In the datasheet example, a 10V DC is connected at the output, so that one can check codmo1010 variation in voltage with a voltmeter or an oscilloscope. How the optocoupler Type SFH acts when the positive line is open. There is no law governing all things. Learn how your comment data is processed. Hi, First of all thanks for sharing such an useful information. Please correct the pin numbers in image.

Wade on February 5, at 9: Pls let me know. Viliam on September 7, at 1: 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 vosmo1010 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. Mihai on November 20, at 1: Better check the datasheet for a test circuit.

Mihai on March 18, at The optocoupler is FL C F, should i just join the emittor and collector pins? Emprical method you mention above or the testing circuit on the datasheet of H11B1? Mihai on August 27, at Mohamed datasheeg October 9, at 9: I hope it datasheey. Any help would be apreciated.

Did you reffer to isolation resistance when you mention some phototransistors have high resistance? The question is which one is the right testing method? Cosm1010 have two circuits.

What if there is photo-Triac instead of Photo-transistor, How to test then? Sanu sebastian on August 19, at I was wondering if i could just bypass the optcoupler and see if it works. 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.

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. Geert Van Droogenbroeck on November 18, at 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.

Hi, maybe a stupid question: Mihai on July 19, at 3: If i give the input of V DC what will be the response of this optocoupler…. This site uses Akismet to reduce spam.

I appriciate… I tried that emprical method for H11B1 optocoupler.

I use analog ohmmeter with 2 internal batteries, 3V to turn on LED pins 1 and 2and digital V-metar on diode tester mode on transistor side. Leave a Reply Cancel reply Your email address will not be published. The datasheeg never solved anything, but neither did water or milk.

Sarfaraz on November 8, at 9: I was referring to the junction resistance. Evis on November 12, at 7:
