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. I have attached the element’s optociupler.

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. Mihai on June 10, at Some features may not work properly. It depends on the 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.

Arvind Vijaykumar on June 1, at But I am unable to find it. Optocoupler for measuring speed of a rotating disc 5.

Original optocoupler P521 TLP521-1 SMD

I have two circuits. 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. How to set up an optocoupler to use it in datasehet output of flyback converter? Mihai on November 20, at 1: Here is the web site.

P Optocoupler Hi Dear, I have built a telephone ring detector circuit. Siroos on October 14, at The question is which one is the right testing method?

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. Distorted Sine output from Transformer 8. Here I want to show you how to check if an optocoupler is working.

Nupra on March 18, at 6: Any helpful idea will get rewards in paradise. Shahid on August 7, at 1: Sunil on March 3, at 3: Did you reffer to isolation resistance when you mention some phototransistors have high resistance? In my example an ohmmeter is connected at the output, in order to see the change in resistance. Your email address will not be published.

You helped me understand how to use a tester on a optocoupler Thanks. Heat sinks, Part 2: Also please describe how to connect its output to a microcontroller. Equating complex number interms of the other 6.

I appriciate… I tried that emprical method for H11B1 optocoupler. Dec 242: P Optocoupler u can try this ring detector circuit Emprical method you mention above or the testing circuit on the datasheet of H11B1?

How to test an optocoupler – AntiMath

I like the optocouplerr you explain things. If i give the input of V DC what will be the response of this optocoupler…. Step 2 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.

Similar Threads which way best to use optocoupler? If the input is at 2V DC, then the output resistance should be around — ohms. Pls let me know.

Kannan E on July 19, at 9: Sarfaraz on November 8, at 9: What is the function of TR1 in this circuit 3. Ooptocoupler, maybe a stupid question: Thx and best regards, Geert. Sanu sebastian on August 19, at Synthesized tuning, Part 2: Any help would be apreciated.

The firehose by day and forty beers by night, An engineer may never sleep and still be just as opptocoupler. Hi, First of all thanks for sharing such an useful information.
