Did you reffer to isolation resistance when you mention some phototransistors pc123 optocoupler high resistance? When Firefox stops working, you fire up Chrome.

Sunil on March 3, at 3: Pc123 optocoupler 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 pc213 we should check the phototransistor, you could measure pc123 optocoupler with the ohmmeter just like pc123 optocoupler LED between pins 3 and 4 the emitter and collectoropticoupler you should get a high resistance value both ways if the phototransistor is good.

The problem is, that I’m not quite sure if this optocoupler can be used for this circuit. The input pc123 optocoupler 5V. These information optocouplet very good indeed.

I only have a digital multi meter. The MIDI specification calls for a high-speed optocoupler.

I have two circuits. If you don’t want to buy a suitable optocoupler like the 6N, 6N, or H11L1, you could try to use additional circuitry to prevent the phototransistor pc123 optocoupler saturating and to pc123 optocoupler its signal:.

Mihai pc123 optocoupler February 6, at Sanu sebastian on August 19, at pc123 optocoupler You have JavaScript disabled or are viewing the site on a device that does no support JavaScript. For the triac pins 4 and 6with no voltage applied to the LED pins 1, 2check with an ohmmeter the resistance between optocouoler 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 pc1223 the voltage is pc123 optocoupler longer present on the LED.

Thanks for the easy to follow explanation of how to rest an optocoupler. Geert Van Droogenbroeck on November 18, at Mihai on July 15, at 8: Wade on February 5, at 9: Please correct pc123 optocoupler pin numbers in image.

Thx pc123 optocoupler best regards, Geert. Save my name, email, ophocoupler website in this browser for the next time I comment.

Thank you for the information. Leave a Reply Cancel reply Your email pc123 optocoupler will not be published.

Any help would be apreciated. The firehose by day and forty beers by night, An engineer may never sleep and still optocpupler just as bright. In the optocouplre example, a 10V DC is connected at the output, so that one can check the variation in voltage opocoupler a voltmeter or an oscilloscope. In my example an ohmmeter is connected at the output, in order to see the change in resistance.

I hope it helps. It depends on the 2nd circuit pc123 optocoupler 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 pc123 optocoupler collector and emitter on pc123 optocoupler input of circuit2.

Shahid on August 7, at 1: How can i test them? I think that the maximum ratings are acceptable but maybe I’m pc123 optocoupler some details.

Hi, Both methods are correct. Mihai on November 20, at 1: Pls let me know.
