Muhammad Akhlaq on May 30, at 9: Save to parts list Save to parts list. Evis on November 12, at 7: Good design is as little design as possible. Emprical method you mention above or the testing circuit on the datasheet of H11B1?

Thank you for your feedback.

By clicking the accept button below, you agree to the following terms. Thank you for the information… and i have one more clarifications. 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.

Hi, First of all thanks for sharing such an useful information. Each In a Pack of Nupra on March 18, at 6: Sunil on March 3, at 3: I guess, it should work mostly the same as a normal triac.

Better check the datasheet for a test circuit. You helped me understand how to use a tester on a optocoupler Thanks. The Manufacturers reserve the right to change this Information at any time without notice.

Thx and best regards, Geert.

Step 2 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. Hi, The MOC, is a phototriac coupler, meaning photocou;ler instead of the phototransistor, it has a phototriac, which is basically a triac with the gate driven by the LED.

These information are very good indeed. There is no law governing all things. 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. Any help would be apreciated. The optocoupler is FL C F, should i just join the emittor and collector pins?

Here is the web site. 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. I like the way you explain things. Sarfaraz on November 8, at 9: Mihai on July 19, at 3: Save this item to a new parts list. Mihai on February 2, at 5: I only have a photocouplsr multi meter. The product detailed below complies with the specifications published by RS Components.

In my example an ohmmeter is connected at the output, in order to see the change in resistance.
