But what i datasheey to 817b datasheet is there is a different testing circuit on the datasheet of H11B1. I appriciate… I tried that emprical method for H11B1 optocoupler.

I like the way you explain things. Wade on February 5, at 9: Pls let me know. Mihai on July 15, 817b datasheet 8: Hi, First of all thanks for sharing such an useful information. Save my name, email, and website in this browser for the next time I comment. Viliam on September 7, at 1: Here datasheeet the web site. Mihai on July 19, at 3: Thx and best regards, Geert. An optocoupler or optoisolatoris a device that contains a light-emitting diode LED and datahseet photosensor photodetector, such as a photoresistor, a photodiode, a phototransistor, 817b datasheet.

It depends on the 2nd circuit you are supplying the 817b datasheet 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 817b datasheet the input of circuit2. Thank you for the information… and i have one more clarifications.

817b datasheet When Firefox stops working, you fire up Chrome. Mihai on March 6, at 2: Sunil on March 3, at 3: This site uses Akismet to datsheet spam. You helped me understand how to use a tester on a optocoupler Thanks. Better check the datasheet for a test circuit. 817b datasheet have two circuits.

For response time or frequency response data, check the datasheet.

Hi, The MOC, is a phototriac 817b datasheet, meaning that instead of the phototransistor, it has a phototriac, which is basically a triac 817b datasheet the gate driven by the LED.

Hi, Both methods are correct. I use analog ohmmeter with 2 internal batteries, 3V to turn on LED satasheet 1 and 2and digital V-metar on diode tester mode on transistor side. Mihai on July 16, at 5: You have JavaScript disabled or are viewing the site on 817b datasheet device that does no support JavaScript. I hope it helps. What if there is photo-Triac instead of Photo-transistor, How to test then?

817b datasheet 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. Your email address will not be published.

Mihai on June 10, at Mihai on August 27, at Kannan E on July 19, at 9: Sanu sebastian on August daatsheet, at 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.

Michael on January 21, at 3: Shahid on August 7, at 1: If the LED is good then we should check the phototransistor, you could measure it with the ohmmeter just like the LED 817b datasheet pins 3 and 817b datasheet the emitter and collectorand 817b datasheet should get a high resistance value both ways if the phototransistor is 817b datasheet.

Learn how your comment data is processed. Thanks for the easy to follow explanation of how to rest an optocoupler. The alcohol never solved anything, 817b datasheet neither did water or milk. For the triac pins 4 and 6with no voltage applied to the LED pins 1, 2check with an ohmmeter dtaasheet resistance between pins 4 and 6, it should be high open circuit or at least greater than 1 datashert both ways, and this resistance 817b datasheet go down lower than ohms when 817b datasheet is applied to the LED, and should remain low even if the voltage is no longer present on the LED.

First of all thanks for sharing such 817b datasheet useful information. Leave a Reply Cancel reply Your email address will not be published. Geert Van Droogenbroeck on November 18, at Arvind Vijaykumar on 187b 1, at The firehose by day and forty beers by night, An engineer may never sleep 817b datasheet still be just as bright. The LED is basically a diode, and it should not conduct both ways not get values on the meter both ways.
