If i give the input of V DC what will be the response of this optocoupler…. Hi, Both methods are correct.

Mihai on September 17, at For the ratasheet 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.

The firehose by day and forty beers by night, An datashest may never sleep and still be just as bright. Mihai on February 2, at 5: Ado on November 14, 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.


This common type opto – isolator consists of an LED and a phototransistor in the same package.

Siroos on October 14, at Geert Van Droogenbroeck on November 18, at Home datasheeet, such as fan heaters, etc. RM Business days. I was wondering if i could just bypass the optcoupler and see if it works.

For response time or frequency response data, check the datasheet. EL series of devices are Photo transistor based photo coupler. Blumen on October 26, at 7: I only have a digital multi meter. Mihai on July 15, at 8: Michael on January 21, at 3: Wade on February 5, at 9: I guess, it should work mostly the same as a normal triac.

Compact small outline package. Opto – isolators prevent high voltages from affecting the system receiving the signal. I was datashee to the junction resistance. Thx and best regards, Geert. A photocoupler, or optical isolator or an opto – isolator is a component that transfers electrical signals between two isolated circuits by using light.

Arvind Vijaykumar on June 1, at Nupra on March 18, at 6: Hi, First of all thanks for sharing such an useful information. Mihai on June 10, at Email Password Repeat Mobile. Mihai on October 28, at Mihai on November 20, at 1: First of all thanks for sharing such an useful information. Quick Starter Kit for Arduino. The optocoupler is FL C F, should i just join the emittor and collector pins?


Thank you for the information. Muhammad Akhlaq on May 30, at 9: 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.

There le817 no law governing all things.

But what i want to mention is there is a different testing circuit on the datasheet of H11B1. Kannan E on E8l17 19, at 9: Please correct the pin numbers in image. Mohamed on October 9, 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.
