If the input is at 2V DC, then the output resistance should be around — ohms. Here I want fatasheet show you how to check if an optocoupler is working.

Wade on February 5, at 9: Mihai on August 27, at These information are very good indeed. Mihai on July 16, at 5: The nice thing about standards is that you have so many to choose from.

In the datasheet example, a 10V DC is connected at the output, so that one can check the 81a7 in voltage with a voltmeter or an oscilloscope. If the LED is good datasheft 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.

Thank you for the information.

Evis on November 12, at 7: I have two circuits. Mihai on September 17, at Thx and best regards, Geert.

Siroos on October 14, at Mohamed on October 9, at 9: But what i want to mention is there is a different testing circuit on the datasheet of H11B1.

How can i test dztasheet I was wondering if i could just bypass the optcoupler and see if it works. The purpose of an optocoupler is to transfer signals from one circuit to another yet keep them galvanically isolated. Mihai on March 18, at You helped me understand how to use a tester on a optocoupler Thanks.

There is no law governing all things. Arvind Vijaykumar on June 1, at Mihai on June 10, at The optocoupler is FL C F, should i just join the emittor and collector pins?

I guess, it should work mostly the same as a normal triac. Nupra on March 18, at 6: For response time or frequency response data, check the datasheet. Step 2 If the LED is good then we should check the 817x, you could dataeheet 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.

Sarfaraz on November 8, at 9: Thank you for the information… and i have one more clarifications. Hi, First of all thanks for sharing such an useful information. Emprical method you mention above or the testing circuit on the datasheet of H11B1? Leave a Reply Cancel reply Your email address will not be published. Mihai on July 19, at 3: Hi, maybe a stupid question: Geert Van Droogenbroeck on November 18, at Good design is as little design as possible.
