Commodity Model:WDYJ-0202
Commodity Category: Optocoupler
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.
OPTOCOUPLER CHARACTERISTICS: Pure resistance material, Non-polar output
The simple circuit structure suitable for DC or AC applications
Good isolation between input and output, Low distortion coupling
TYPICAL APPLICATIONS:
Audio amplifier protection and control
Audio volume limiting
Electric shielded isolation coupling
Communication transmission and Automatic control
Lights adjustment and Motor speed control
