Mihai on August 27, at Mihai on June 10, at I guess, it datasheef work mostly the same as a normal triac. Here I want to show you how to check if an optocoupler is working.
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. The firehose by day and forty beers by night, An engineer may never sleep datasjeet still be just as bright. Mihai on March 6, at 2: In the datasheet example, a 10V 81a is connected at the output, so that one can check the variation in voltage with a voltmeter or an oscilloscope. You helped me understand how to use a tester on a optocoupler Thanks.

817a datasheet pdf
Mihai on July 16, at 5: I was referring to the junction resistance. Any help would be apreciated. Learn how your comment data is processed.
The nice thing about standards is that you have so many to choose from. When Firefox stops working, you fire 817 Chrome. Sarfaraz on November 8, at 9: Michael on January 21, at 3: So when current flows through the LED, the triac is triggered and it conducts both ways until the main current drops below 8817a certain level. Evis on November 12, at 7: 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.
Mohamed on October 9, at 9: The LED is basically a diode, and it should not conduct both datassheet not get values on the meter both ways.
How to test an optocoupler – AntiMath
Ado on November 14, at Sanu sebastian on August 19, at Mihai on November 20, at 1: Hi, Both methods are correct. Mihai on September 17, at I hope it helps. This site uses Akismet to reduce spam. How the optocoupler Type SFH acts when the positive line is open.
I appriciate… I tried that emprical method for H11B1 optocoupler. Here is the web site.
I like the way you explain things. First of all thanks for sharing such an useful information.
Hi, maybe a stupid question: I was wondering if i could just bypass the optcoupler and see if it works. Mihai on July 19, at 3: Emprical method you mention above or the testing circuit on the datasheet of H11B1?
a datasheet pdf
Nupra on March ddatasheet, at 6: For response time or frequency response data, check the datasheet. Muhammad Akhlaq on May 30, at 9: How can i test them? But what i want to mention is there is a different testing circuit on the datasheet of H11B1. Arvind Vijaykumar on June 1, at Did you reffer to isolation resistance when you mention some phototransistors have high resistance?
Mihai on October 28, at I only have a digital multi meter. Geert Van Droogenbroeck on November 18, at What if there is photo-Triac instead of Photo-transistor, How 817w test then? Thx and best regards, Geert.
