What is necessary is to ensure that R1 creates an appropriate current level from the input circuit to correctly drive the LED side of the optocoupler, and that R2 creates appropriate voltage and current
Applications of Optocoupler As discussed before few Optocoupler used in DC circuit and few Optocoupler used in AC related operations. As the
An optoisolator (also called optocoupler) is a device that uses light to couple a signal from its input (a photoemitter e.g., a LED) to its output (a photodetector e.g., a photo-diode). The
Optocoupler Principle Optocouplers are used to isolate sections of a circuit that are incompatible in terms of the voltage levels or currents required.
The basic working principle of Optocoupler is the output of the electrically isolated circuit is controlled by varying the input of the circuit. Input is
The working principle of an Optocoupler The input impedance of the photocoupler is a small value that is about some hundred ohms and the
