The function of optocouplers
Due to the wide variety of optocouplers, unique structures, and outstanding advantages, they are widely used, mainly in the following situations:
(1) Application in Logic Circuits
Optocouplers can form various logic circuits, and due to their better anti-interference and isolation performance than transistors, logic circuits composed of optocouplers are more reliable.
(2) As a solid-state switch application
In switch circuits, it is often required to have good electrical isolation between the control circuit and the switch, which is difficult to achieve for general electronic switches, but it is easy to achieve with optocouplers.
(3) Application in trigger circuits
The use of optocouplers in bistable output circuits can effectively solve the problem of output and load isolation by connecting the light-emitting diodes in series into two emitter circuits.
(4) Application in Pulse Amplification Circuit
Optocouplers are used in digital circuits to amplify pulse signals.
(5) Application in Linear Circuits
Linear optocouplers are applied in linear circuits and have high linearity and excellent electrical isolation performance.
(6) Application in special occasions
Optocouplers can also be used in high-voltage control, replacing transformers, replacing contact relays, and in various applications such as A/D circuits.
