What are Optocouplers, Photocouplers, and Optoisolators?
In these, an optical coupling is used to isolate the input and output electrically, while allowing the output to switch based on the input state. Because of their versatility, optocouplers are
Home / Optocoupler is equivalent to optical coupler
An optocoupler, also known as photocoupler or opto-isolator, is a device which can transfer an electrical signal across two galvanically-isolated circuits by way of optical coupling. Unlike transformers or capacitors, which can only transfer AC signals across the isolation barrier, optocouplers can. The photocouplers or optocouplers are typically contained in a single package, often about the. This process ensures there is no direct electrical connection between the input (source) and the output (load), effectively protecting sensitive low-voltage components.
In these, an optical coupling is used to isolate the input and output electrically, while allowing the output to switch based on the input state. Because of their versatility, optocouplers are
