Wade on February 5, at 9: The nice thing about standards is that you have so many to choose from. Check out this bundle:. Transistor Output – Bipolar, Cosmo Electronics.
Here I want to show you how to check if an optocoupler is working. Please correct the pin numbers in image. Bipolar transistor output opto-couplers from Cosmo Electronics. Ado on November 14, at The question is which one is the right testing method?
Forward Current If AV: It uses the PC optoisolator. A photocoupler, or optical isolator or an opto – isolator is a component that transfers electrical signals between two isolated circuits by using light.

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 July 15, at 8: Opto – isolators prevent high voltages from affecting the system receiving the signal. 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.
Thank you for the information. What if there is photo-Triac instead of Photo-transistor, How to test then?

I was wondering if i could just bypass the optcoupler and see if it works.

I have two circuits. Current Transfer Ratio Min: Both single and dual through-hole devices are available as well as a single-channel SMT version. Mihai on February 2, at 5: The optocoupler is FL C F, should i just join the emittor and collector pins?
If the input is at 2V DC, then the output resistance should be around — ohms. 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. Pick up procedure is as follows. Any phohocoupler would be apreciated.
