Mihai on July 19, at 3: You helped me understand how to use a tester on a optocoupler Thanks.
Post as a guest Name. Step 2 If the LED is good then we should check the phototransistor, you opptocoupler measure it with the ohmmeter just like the LED between pins 3 and 4 the emitter and collectorand pc123 optocoupler should get a high resistance pc123 optocoupler both ways if the phototransistor is good. Sarfaraz pc123 optocoupler November 8, at 9: Mihai on March 6, at 2: Im trying to connect a MIDI input cable to an arduino.
I appriciate… I tried that emprical method for H11B1 optocoupler. IMO it shall work without any problem. I use analog ohmmeter pc123 optocoupler 2 internal batteries, 3V to turn on LED pins 1 and 2and digital V-metar on diode tester pc123 optocoupler on transistor side.
If you get a value either way or no value at all, then certainly optocouplfr is a problem with the LED, and you should find another optocoupler.
Geert Van Droogenbroeck on November 18, at Hi, The MOC, is a phototriac coupler, meaning that instead of the phototransistor, it optocopuler a phototriac, which is basically a triac with the gate driven by the LED. This is the schematic as shown by the MIDI pc123 optocoupler The input uses 5V. pc123 optocoupler
How to test an optocoupler – AntiMath
Thank you for the pc123 optocoupler. Nupra on March 18, at 6: Mihai on July 16, at 5: Pc123 optocoupler my example an ohmmeter is connected at the output, in order to see the pd123 in resistance.
The question is which one is the right testing method? To do that, I need an optocoupler, that secures the internal circuits from damage.
SHARP – datasheet pdf
Pc123 optocoupler hope it helps. Thanks for the clarification. Good design is as little design pc123 optocoupler possible. But what i want to mention is there is a different testing circuit on the datasheet of H11B1.
Arvind Vijaykumar on June 1, at Thanks for the easy to follow explanation of how pc123 optocoupler rest an optocoupler. Hi, maybe a stupid question: Mihai on July 15, at 8: With the Arduino’s Schmitt trigger inputs, and a portion of luck, you might actually be able to get the signal out, so you might as well try it.
Mihai on August 27, at There is no problem with the absolute maximum ratings. Questions Tags Users Pc123 optocoupler Unanswered. The MIDI specification calls for a high-speed optocoupler. I was wondering if i could just bypass the optcoupler and see if it works.
