reflective optocouplerssensors for roboticsDue to its numerous qualities, namely their low cost, infrared reflective optocouplers are of large use in the industry to detect an object passing in their field of view. They nevertheless are mainly limited to deliver a pure dichotomic information. The ...
Or when you actually use the photocoupler in your own electronics work, you may not know how to choose and use it. Because optocoupler is often confused with “phototransistor” and “photodiode”. Therefore, what is a photocoupler will be introduced in this article. What is a photocoupler?
Later I experimented with two-way optocouplers made by taping a pair of LEDs together so they faced one another. In 1988, I tried LEDs as sunlight detectors. They worked so well that the first homemade LED sun photometer I began using on Feb. 5, 1990, is still in use today. Why ...
37 Chapter 4 Synopsis of Key Regulatory Specifications 4.0 How To Use The Regulatory Synopsis Information Chapter 4 contains a brief regula- tory summary of key electrical safety requirements of each of the International or National safety standards addressed in Chapter 3. These summaries only address...
Discussing the use of Optocoupler using LDR/LED My good friend, Mr. Chiverton, shared his experience regarding the features of an LDR in comparison to phto-transistors for making opto couplers. I have explained what he discovered regarding optocouplers during his experience with my ghost detector...
The third circuit uses a PC817 optocoupler. The input side uses an internal LED, the LED is rated for 1.2V and 20mA. I can connect one to the DC power supply and see at 1.2V the current is 0.02A so we will use this value. On the input side we will use a switch to control the...
In most cases, an optocoupler is employed to isolate the high voltage side of this setup. Apart from that, the IC can be used in a variety of circuits where a Zener diode can be utilized, but only a handful of them. TL431 Feature AEC-Q100 qualified Adjustable output voltage...

CISO is the sum of the isolation/barrier capacitances of all of the isolation elements used (isola- tors, optocouplers, transformers) and any capacitance introduced by the printed circuit board. You can create electrical models of the different tran- sient events using the voltage and current ...
