[34]CALCULATE OPTOCOUPLER VOLTAGE AND AMPERAGE FOR A CIRCUIT

An optocoupler (also called optoisolator) is a semiconductor device that allows an electrical signal to be transmitted between two isolated circuits. Two parts are used in an optocoupler: an LED that emits infrared light and a photosensitive device that detects light from the LED. Both parts are contained within a black box with pins for connectivity. The input circuit takes the incoming signal, whether the signal is AC or DC, and uses the signal to turn on the LED.
The photosensor is the output circuit that detects the light and depending on the type of output circuit, the output will be AC or DC. Current is first applied to the optocoupler, making the LED emit an infrared light proportional to the current going through the device. When the light hits the photosensor a current is conducted, and it is switched on. When the current flowing through the LED is interrupted, the IR beam is cut-off, causing the photosensor to stop conducting.

Thank you sir ❤❤❤

Btw sir with optocoupler output it might possible to measures the current but how to measure voltage

[@hobby_plus]

witch voltage do you want to measures, output or input?

[@vishalr4551]

@@hobby_plus i need measure input voltage by output of the optocoupler by a microcontroller

[@hobby_plus]

I don't understand your question?
