Ado datasneet November 14, at Hi, Both methods are correct. Sarfaraz on November 8, at 9: 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.

Mihai on March 6, at 2: Some features may not work properly. Thx and best regards, Geert. Good design is as little design as possible. Here I want to show you how to check if an optocoupler is working.

For the triac pins 4 and 6with no voltage applied to the LED pins 1, 2check with an ohmmeter the resistance cosmo010 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 Datssheet.


The optocoupler is FL C F, should datashee just join the emittor and collector pins? It depends on the 2nd circuit you are supplying the voltage 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 on the input of circuit2.

Sanu sebastian on August 19, at I was wondering if i could just bypass the optcoupler and see if it works. With no voltage applied to the LED pins 1 and 2and with an open cozmo1010 pin 6there should be a high resistance between pins 5 and 4.

Mihai on September 17, at Muhammad Akhlaq on May 30, at 9: Did you reffer to isolation resistance when you mention some phototransistors have high resistance? Better check the datasheet for a test circuit.

Viliam on September 7, at 1: Thank you for the information… and i have one more clarifications. Wade on February 5, at 9: I hope it helps. Michael on January 21, at 3: The nice thing about standards is that you have so many to choose from.

Please correct the pin numbers in image. The purpose of an optocoupler is to transfer signals from one circuit to another yet keep them galvanically isolated. If the input is at 2V DC, then the output resistance should be around — ohms. Blumen on October 26, at 7: Cpsmo1010 optocoupler or optoisolatoris a device that contains a light-emitting diode LED and a ddatasheet photodetector, such as a photoresistor, a photodiode, a phototransistor, …etc. I have two circuits.


Evis on November 12, at 7: What if there is photo-Triac instead of Photo-transistor, How to test then? Learn how your comment data is processed.

Datashwet you for the information. But what i want to mention is there is a different testing circuit on the datasheet of H11B1. You have JavaScript disabled or are viewing the site on a device that does no support JavaScript.

I only have a digital multi meter. Hi, First of all thanks for sharing such an useful information. Siroos on October 14, at I guess, it should work mostly the same as a normal triac.
