The alcohol never solved anything, but neither did water or milk. Hi, First of all thanks for sharing such an useful information. Your email address will not be published.

Mihai on February 6, at Mihai on June 10, at Any help would be apreciated. I was wondering if i could just bypass the optcoupler and see if it works.

Hi, maybe a stupid question: If you get a value either way or no value at all, then certainly there is a problem with the LED, and you should find another optocoupler. Step 2 If the LED is good then we should check dataseet 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. Emprical method you mention above or the testing circuit on the datasheet of H11B1?

Mihai on July 19, at 3: Thx and best regards, Geert. Shahid on August 7, at 1: With no voltage applied to the LED pins 1 and 2and with an open base pin 6there should be a high dafasheet between pins 5 and 4.

The dayasheet of an optocoupler is to transfer signals from one circuit to another yet keep them galvanically isolated. Siroos on October 14, at How can i test them? The nice thing about standards is that you have so many to choose from. Leave a Reply Cancel reply Your email address will not be published.

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