The question is which one is the right testing method? In dtasheet 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. You have JavaScript disabled or are viewing the site on a device that does no support JavaScript. I use analog ohmmeter with 2 internal batteries, 3V to turn on LED pins 1 and 2and digital V-metar on diode tester mode on transistor side.

If you get a value either way or no value at all, then certainly there is a problem with datasheeh LED, and you should find another optocoupler. What if there is photo-Triac instead of Photo-transistor, How to test then? Any help would be apreciated. Leave a Reply Cancel reply Your email address will not be published.

Mihai on July 16, at 5: Thank you daasheet the information… and i have one more clarifications.

Mohamed on October 9, at 9: When Firefox stops working, you fire up Chrome. Here I want to show you how to check if an optocoupler is working. Your email address will not be published. The nice thing about standards is that you have so many to choose from. Mihai on February 6, at I appriciate… I tried that emprical method for H11B1 optocoupler.

With no voltage applied to the LED pins 1 and 2and with an open base pin 6there should be a high resistance between pins 5 and 4. If the input is at 2V DC, then the output resistance should be around — ohms.

Thank you for the information. Sunil on March 3, at 3: 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. Siroos on October 14, at I was wondering if i could just bypass the optcoupler and see if it works.

The alcohol never solved anything, but neither did water or milk. Blumen on October 26, at 7: Learn how como1010 comment data is processed. Mihai on March 18, at You helped me understand how to use a tester on a optocoupler Thanks. The purpose of an optocoupler is to transfer signals from one circuit to another yet keep them galvanically isolated.

But what i want to mention is there is a different testing circuit on the datasheet of H11B1. The optocoupler is FL C F, should i just join the emittor and collector pins? Evis on November 12, at 7: Shahid on August 7, at 1: For response time or frequency response data, check the datasheet.

Thx and best regards, Geert. This site uses Akismet to reduce spam.

Geert Van Droogenbroeck on November 18, at 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.

Sarfaraz on November 8, at 9: I have two circuits. Mihai on February 2, at 5: How the optocoupler Type SFH acts when the positive line is open. Hi, First of all thanks for sharing such an useful information. Hi, maybe a stupid question: If i give the input of V DC what will be the response of this optocoupler….

Datashert you reffer to isolation resistance when you mention some phototransistors have high resistance?

Please correct the pin numbers in image. 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.
