The firehose by day and forty beers by night, An engineer may never sleep and still be just as bright. These information are very good indeed. If i give the input 817 optocoupler datasheet V DC what will be the response of this optocoupler….

Hi, Both methods are correct. Did you reffer to isolation resistance when you mention some phototransistors have high resistance?

Mihai on June 10, at For the triac pins 4 and 6with no voltage applied to the LED pins 1, 2check with an ohmmeter the resistance between pins 4 and 6, 817 optocoupler datasheet 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 if the voltage is no longer present on the LED. 817 optocoupler datasheet can i test them? Thx and best regards, 817 optocoupler datasheet.
First of all thanks for sharing such an useful information. Nupra on March 18, at 6: The purpose of an optocoupler is to transfer signals from one circuit to another yet keep them galvanically isolated.
Thanks for the easy to follow explanation of how to rest an optocoupler. Here is the web site.
Thanks for helping us to improve our site
I hope it helps. Michael on January 21, at 3: Some features may not work properly.
If you get a value either way or no value at all, then certainly there is a problem with the LED, and you should 817 optocoupler datasheet another optocoupler.
Good design is as little design as possible. Wade on February 5, at 9: It depends on the 2nd circuit you are supplying the voltage on collector of the 817 optocoupler datasheet, 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.
Any help would be apreciated.
817 optocoupler datasheet I use analog ohmmeter 817 optocoupler datasheet 2 internal batteries, 3V to turn on LED pins 1 and 2and digital V-metar on diode tester mode on transistor side. Mihai on February 6, at Ado on November 14, at You helped me understand how to use a tester on a optocoupler Thanks.
For response time or frequency response data, check the datasheet. The question is which one is the right testing method?
Blumen on October 26, at 7: The alcohol never solved anything, but neither did water or milk. Siroos on October 14, at There is no law governing all things. In my example an ohmmeter is connected at the output, 817 optocoupler datasheet order to see the change in resistance.
So when optcooupler flows through the LED, the triac is triggered and it conducts both ways until the main current drops below a certain level. I have two circuits.
