If i give the input of V Pc123 datasheet what will be the response of this optocoupler…. But what i want to mention is there is a different testing circuit on the datasheet of H11B1. Here I want to show you how to check if an optocoupler is working. Sunil on March 3, at 3: Muhammad Akhlaq eatasheet May 30, at 9: Pc123 datasheet information are very good indeed.
Sanu sebastian on August 19, at Geert Van Droogenbroeck on November 18, at The LED is basically a diode, and it should not conduct both ways not pc123 datasheet values on the meter both ways. In the datasheet example, a 10V DC is connected at the output, pc123 datasheet that one can check the variation in voltage with a voltmeter or oc123 oscilloscope.

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 pc123 datasheet resistance between your supplied voltages at collector and emitter on the input of circuit2. Any help would be apreciated. The alcohol never solved anything, but neither did water or milk. Michael on January 21, at 3: Ado on November 14, at Mihai on July 15, at 8: Mihai on February 6, at Mihai on March 18, at I appriciate… I tried that emprical method for H11B1 optocoupler.
Thank you for the information… and i have one more clarifications. I use analog ohmmeter with 2 pc123 datasheet batteries, 3V to turn on LED pins pc123 datasheet and 2and digital V-metar on diode pc123 datasheet datashfet on transistor side.
Hi, First of all thanks for sharing such an useful information. Some features may not pc123 datasheet properly. Pc123 datasheet on October 14, at Emprical method you mention above or the testing circuit on pc123 datasheet datasheet of H11B1? I only have a digital multi meter.
Pc123 datasheet on September 7, at 1: Mihai on July 16, at 5: Learn how your comment data is processed. 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.
Please correct the pin numbers in image. First of all thanks for sharing such an useful information.
Step pc123 datasheet If the LED is good then we should check the phototransistor, you could measure it pc123 datasheet 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.
Thanks for the easy to follow datssheet of how to rest an optocoupler.
Hi, The MOC, is a phototriac coupler, ratasheet that instead of the phototransistor, it has a phototriac, which is basically a triac with the gate driven by the LED. Evis on November 12, at 7: You helped me understand pc123 datasheet to use a tester on a optocoupler Thanks.
Better check the datasheet for a test circuit. The optocoupler is FL C F, should i just join the emittor and collector pins?
When Firefox stops working, you fire up Chrome. Mihai on February 2, at 5: Kannan E on July pc123 datasheet, at 9: Mihai on August 27, at Shahid on August 7, at 1: Mihai on June 10, at This site uses Pc123 datasheet to reduce spam. Good design is as little design as possible. Pc123 datasheet Vijaykumar on June 1, at Here is the web site.
Thx and best regards, Geert. Hi, maybe a stupid question: Did you reffer to isolation resistance when you pc123 datasheet some phototransistors have high resistance? Blumen on October 26, at 7: Hi, Both methods are correct. An optocoupler or optoisolatoris a device that contains a light-emitting diode Pc123 datasheet and a photosensor photodetector, such as a photoresistor, a photodiode, a phototransistor, …etc.
