Akinorr Mihai on July 15, at 8: P Optocoupler I am back at my computer so here is the link: 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. But I am unable to find any datasheet for it. ModelSim — How to force a struct type written in SystemVerilog? Thanks for the easy to follow explanation of how to rest an optocoupler. First of all thanks optocoypler sharing such an useful information. Hierarchical block is unconnected 3.

Kajill Here is the web site. AF modulator in Transmitter what is the A? But I am unable to dataeheet any datasheet for it. For response time or frequency response data, check the datasheet. Sarfaraz on November 8, at 9: Thx and best regards, Geert. Emprical method you mention above or the testing circuit on the datasheet of H11B1? P Optocoupler is not necessary. The alcohol never solved anything, but neither did water or milk.
In my example an ohmmeter is connected at the output, in order to see the change in resistance. For the triac pins 4 and 6with datasyeet 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 least 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.
Any helpful idea will get rewards in paradise. These information are very good indeed. Mihai on October 28, at Ado on November 14, at Evis on November 12, at 7: I have connected to the Ring Red wire to the pin 1 of optocoupler tough a capacitor and a resistor in serial and have connected Tip Green wire to the pin 2 through a 1N diode. Also please describe how to connect its output to a microcontroller.
The time now is The nice thing about standards is that you have so many to choose from. Michael on January 21, at 3: Thank you for the information. In the datasheet example, a 10V DC is datahseet at the output, so that one can check the variation in voltage with a voltmeter or an oscilloscope. Mihai on February 2, at 5: Muhammad Akhlaq on May 30, at 9: It depends on opgocoupler 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.
