Description
Optocoupler is a device that is mainly made of LED & Photocell. It is also called opto-isolator, optical isolator, photocoupler. The input element is LED and output element is the photocell. When there is current is applied to the LED, the output photocell turns on. They work together to provide electrical isolation. That is, there is a short optical transmission path to transfer a signal between LED and Photocell, while keep them electrically isolated.
Applications
Audio amplifier protection and control
Electric shielded isolation coupling
Communication transmission and Automatic control
Lights adjustment and Motor speed control
Industrial, Motor Drive & Control
Main characteristic curve
Attention : Soldering pin recommended away from the bottom of optocoupler, soldering time should be as short as possible.
