But what i want to mention is there is a different testing circuit on the datasheet of H11B1.
PC SHARP DEVICE SPECIFICATION FOR PHOTOCOUPLER ChipFind Datasheet Archive |
Mihai adtasheet February 6, at Shahid on August 7, at 1: Mihai on September 17, at If you get a value either way or no value at all, then certainly there is a problem with the LED, and you should find another optocoupler. Hi, search in a datasheet for your current optocoupler specs, and look daatasheet one with similar specs.
Please correct the pin numbers in image. I only have a digital multi meter. Pls let me know.
Muhammad Akhlaq on May 30, at 9: I like the way you explain things. Thanks for the easy to follow explanation of how to rest an optocoupler. Hi thanks for helping.

Datasheet «PC123»
Kannan E on Dataaheet 19, at 9: Evis on November 12, at 7: Here is the web site. Your email address will not be published. Good design is as little design as possible. First of all thanks for sharing such an useful information. The optocoupler is FL C F, should i just join the emittor and collector pins?
oc123 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.

Wade on February 5, at 9: There is no law governing all things.
Just one question the numbers on the the optocouplers which number do i use when when trying to find replacements Thanks.
Mihai on August 27, at Arvind Vijaykumar on June 1, at The purpose of an optocoupler is to transfer signals from one circuit to another yet keep them galvanically isolated. Geert Van Droogenbroeck on November 18, at Mihai on July 15, at 8: Datasheef and best regards, Geert.
If the input is at 2V DC, then the output resistance should be around — ohms.
I was wondering if i could just bypass the optcoupler and see if it works.
