Hi, maybe a stupid question: What if there is photo-Triac instead of Photo-transistor, How to test then? Thank you for the information… and i have photodoupler more clarifications. RM Business days.

When Firefox stops working, you fire up Chrome. I guess, it should work mostly the same as a normal triac. Description EL Phototransistor Photocoupler The EL Phototransistor Photocoupler series of devices each consist of an infrared emitting diodes, optically coupled to a phototransistor detector.

Wade on February 5, at 9: Please correct the pin numbers in image. Got one to sell? 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.

First of all thanks for sharing such an useful information. Output Type see all. You helped me understand how to use a tester on a optocoupler Thanks.

Hi, Both methods are correct. Show only see all.

Images shown is only for representation. Great for use in noisy circuits where signal lines require electrical isolation. Geert Van Droogenbroeck on November 18, at Some features may not work properly.

System appliances, measuring instruments. Delivery options see all. I was referring to phktocoupler junction resistance. Muhammad Akhlaq on May 30, at 9: A photocoupler, or optical isolator or an opto – isolator is a component that transfers electrical signals between two isolated circuits by using light. How can i test them? Mihai on February 6, at The LED is basically a diode, and it should not conduct both ways not get values on the meter both ways.

Here at Keatronics we have many years experience in the electronics industry.

Forward Current If AV: Add to Wish List Compare this Product. Any help would be apreciated.

Kannan E on July 19, at 9: Opto – isolators prevent high voltages from affecting the system receiving the signal. Mohamed phitocoupler October 9, at 9: The alcohol never solved anything, but neither did water or milk. Mihai on June 10, at Mihai on August 27, at Transistor Output Optocouplers, Lite-On. Mihai on February 2, at 5: Mihai on September 17, at If you get a value either way or no value at all, then certainly there photocokpler a problem with the LED, and you should find another optocoupler.

Electrically neutral thermal path. Mihai on July 16, at 5: 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.

Signal transmission between circuits of different potentials and impedances. Mihai on November 20, at 1: Siroos on October 14, at An opto-isolator connects input and output sides with a beam of light modulated by input current.

More refinements More refinements The actual product may vary with the picture shown. Evis on November 12, at 7: The purpose of an optocoupler is to transfer signals from one circuit to another yet keep them galvanically isolated.

Thank you for the information.
