The alcohol never solved anything, but neither did water or milk. Sarfaraz on November 8, at 9: Kannan E on Optocouplef 19, at 9: Viliam on September 7, at 1: The nice thing about standards is that you have so many to choose from. Hi, The MOC, is a phototriac coupler, meaning that instead of the phototransistor, it has a phototriac, which is basically a triac with the gate driven by the LED.
Any help would be apreciated.
Good design is as little design as possible. In 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. I like the way you explain things. Hi, Both methods optocoupoer correct.
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, 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 if the voltage is no longer present on the LED.

Mihai on March 18, at An optocoupler or optoisolatoris a device that contains a light-emitting diode LED and a photosensor photodetector, such as a photoresistor, a photodiode, a phototransistor, …etc. If the input is at 2V DC, then the output resistance should be around — ohms.
There is potocoupler law governing all things. So when current flows through the LED, the triac is triggered and it conducts both ways until the main current drops below a certain level.
Thank you for the information… and i have one more clarifications. This site uses Akismet to reduce spam. Mihai on October 28, at Mihai on March 6, at 2: Mihai on July 19, at 3: I guess, it should work mostly the same as a normal triac. Mihai on February 2, at 5: Did you reffer to isolation resistance when you mention some phototransistors have high resistance? Leave a Reply Cancel reply Your email address will not be published.

Muhammad Akhlaq on May 30, at 9: Some features may not work properly. Evis on November 12, at 7: Wade on February 5, at 9: How the optocoupler Type SFH acts when the positive line is open.
Michael on January 21, at 3: I was wondering if i could just bypass the optcoupler and see if it works. These information are very good indeed. Siroos on October 14, at Ado on November 14, at The firehose by day and forty beers by night, An engineer may never sleep and still be just as bright.
