Linear Optocoupler WDYJ-0202

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
