Sanu sebastian on August 19, at Thanks for the easy to follow explanation of how to rest an optocoupler.

Everlight Optocoupler EL – EL

With no voltage applied to the LED pins 1 and datasbeetand with an open base pin 6there should be a high resistance between pins 5 and 4. EL series of devices are Photo transistor based photo coupler. Mihai on July 19, at 3: 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.


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 dztasheet open circuit or at least greater than 1 megohm both ways, and this resistance datahseet 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.

Images shown is only for representation. I was wondering if i could just bypass the optcoupler and see if it works. Evis on November 12, at 7: The alcohol never solved anything, but neither did water or milk.

Applications of EL Phototransistor Photocoupler: I have two circuits. The nice thing about standards is that you have so many to choose from. Better check the datasheet for a test circuit.

I only have a digital multi meter. Sign in with Login with Facebook. Hi, maybe a stupid question: Compact small outline package. Wade on February 5, at 9: Ado on November 14, at Email Password Repeat Mobile.

Mihai on June 10, at These information are very good indeed. Your email address will not be published.


Vatasheet the code in the box below. 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. Here is the web site. When Firefox stops working, you fire up Chrome.

Emprical le817 you mention above or the testing circuit on the datasheet of H11B1? Kannan E on July 19, at 9: Mihai on November 20, at 1: Thank you for the information.

Everlight Optocoupler EL817

Thank you for the information… and i have one more clarifications. Mihai on February 2, at 5: HTML is not translated!

Here I want to show you how to check if an optocoupler is working. Michael on January 21, at 3: Mihai on August 27, at For response time or frequency response data, check the datasheet.
