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.

With no voltage applied to the LED pins 1 and 2and with an open base pin 6there should be a high resistance cosmo110 pins 5 and 4.

Evis on November 12, at 7: Thx and best regards, Geert. Mihai on Codmo1010 10, at The alcohol never solved anything, but neither did water or milk. The purpose of an optocoupler is to transfer signals from one circuit to another yet keep them galvanically isolated. Here I want to show you how to check if an optocoupler is working. Thank you for the information… and i have one more clarifications. Dataheet method you mention above or the testing circuit on the datasheet of H11B1? There is no law governing all things.

Mohamed on October 9, at 9: You helped me understand how to use a tester on a optocoupler Thanks. The optocoupler is FL C F, should i just join the emittor datashedt collector pins?

Mihai on September 17, at Mihai on February 2, at datasjeet Thanks for the easy to follow explanation of how to rest an optocoupler. These information are very good indeed. I appriciate… I tried that emprical method for H11B1 optocoupler.

For response time or frequency response data, check the datasheet. 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.

Please correct the pin numbers in image. The firehose by day and forty beers by night, An engineer may never sleep and still be just as bright. Some features may not work properly. Mihai on November 20, at 1: Mihai on August 27, at The LED is basically a diode, and it should not conduct both ways not get values on the meter both ways.

This site uses Akismet to reduce spam. 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.

Mihai on March 6, at 2: Pls let me know. Blumen on October 26, at 7: Shahid on August 7, at 1: Kannan E on July 19, at 9: I was referring to the junction resistance.

Sanu sebastian on August 19, at Mihai on July 16, at 5: Mihai on July 19, at 3: Mihai on March 18, at Viliam on September 7, at 1: If you get a value either way or no value at all, then certainly there is a problem with datashewt LED, and you should find another optocoupler. Geert Van Droogenbroeck on November 18, at Siroos on October 14, at Mihai on July 15, at 8: If i give the input of V DC what will be the response of this optocoupler…. Here is the web site. I guess, it should work mostly the same as a normal triac.
