Check out this bundle:. If the input is at 2V DC, then the output resistance should be around — ohms.

A photocoupler, or optical isolator or an opto – isolator is a component that transfers electrical signals between two datasheer circuits by using light. The EL Phototransistor Photocoupler series of devices each consist of an infrared emitting diodes, optically coupled to a phototransistor detector.

You helped me understand how to use a tester on a optocoupler Thanks.

Leave a Reply Cancel reply Your email address will not be published. Please correct the pin numbers in image. Nupra on March 18, at 6: 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.

Mihai on March 6, at 2: Hi, Both methods are correct.

Mihai on June 10, at Here is the web site. It depends on the 2nd circuit you are supplying the voltage on collector of the dataasheet, 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.

Michael on January 21, at 3: Mohamed on October 9, at 9: 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.

Compact small outline package. Opto – isolators prevent high voltages from affecting the system receiving the signal. For the triac pins 4 and 6with no voltage applied to the LED dafasheet 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.

RM Business days. Mihai on March 18, at These information are very good indeed. Mihai on February 6, at EL series of devices are Photo transistor based photo coupler. The nice thing about el8817 is that you have so many to choose from. Enter your Email Address here to receive a link to change password.

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

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. Geert Van Droogenbroeck on November 18, at HTML is not translated!

Sunil on March 3, at 3: Images shown is only for representation. I have two circuits. The purpose of an optocoupler is to transfer signals from one circuit to another yet keep them galvanically isolated. Wade on February 5, at 9: When Firefox stops working, you fire up Chrome.
