Linear optocoupler
Pure resistor and non-polarity output
Wide range of analog linear resistance, "on" at the low resistance. "off" at the high resistance.
Simple circuit configuration suitable for DC and AC use
Input to output isolation, and low distortion coupling


Optocoupler is a Optoelectronic devices which use the current changes to control the resistance change. It is a Linear optocoupler which through the strictly selected, aging, testing. It made up of CDS and LED. This product belongs to the current input control,non-polarity resistance output control type.
