Interfacing High Power Load to Logic Level with Optocoupler
![](https://freecircuitdiagram.com/wp-content/uploads/2011/02/Optocoupler-that-is-used-as-a-load-to-logic-translator.jpg)
Interfacing high power load can be done in many ways, such as using voltage divider resistors, transformer, or optocoupler. In the circuit shown below , an optocoupler method is presented. This optocoupler serve the logic level translation with flexible input, accepting wide range of voltage level, which is suitable for many high power load/devices. To couple a high-voltage load to […]
