EL817 Datasheet PDF

The actual product may vary with the picture shown. An optocoupler or optoisolatoris a device that contains a light-emitting diode LED and a photosensor photodetector, such as a photoresistor, a photodiode, a phototransistor, …etc. Leave a Reply Cancel reply Your email address will not be published.

Michael on January 21, at 3: Mihai on November 20, at 1: Geert Van Droogenbroeck on November 18, 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. Mihai on July 15, at 8: What if there is photo-Triac instead of Photo-transistor, How to test then?

Hi, maybe a stupid question: I use analog ohmmeter with 2 internal batteries, 3V to turn on LED pins 1 and 2and el17 V-metar datasheft diode tester mode on transistor side. Mihai on October 28, at Applications of EL Phototransistor Photocoupler: Description EL Phototransistor Photocoupler The EL Phototransistor Photocoupler series of devices each consist of an infrared emitting diodes, optically coupled to a phototransistor detector.

Step 2 If the LED is good then we should check the phototransistor, you could measure it with the ohmmeter just dxtasheet 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. Thx and best regards, Geert.

This common type opto – isolator consists of an LED and datasheey phototransistor in the same package. Enter your Email Address here to receive a link to change password.

How can i test them? When Firefox stops working, you fire up Chrome.

I only have a digital multi meter. Mihai on March 6, at 2: Ado on November 14, at I appriciate… I tried that emprical method for H11B1 optocoupler. Signal transmission between circuits of different potentials and impedances.

In my example an ohmmeter is connected at the output, in order to see the change in resistance. Blumen on October 26, at 7: The EL Phototransistor Photocoupler series of devices each consist of an infrared emitting diodes, optically coupled to a phototransistor detector.
