Plz can u tell me what is optisolator....?
It is an LED and a Photo-transistor. When the LED is illuminated the photo-transistor goes from cutoff to saturation. When the LED is dark the photo-transistor returns to cutoff. The photo-transistor can be configured as a common emitter switch or as an emitter follower depending on weather you want the output to be inverting or non-inverting. The chief reason for using one is to provide isolation between the input circuit and the output circuit.Can you tell me what an optoisolator is please?
