WHAT IS EACH INPUT AND OUTPUT PRT CONNECTED TO THE CPU THROUGH AN OPTOISOLATOR CHIP SUCH AS THE 4N32?
In a system using an optoisolator chip like the 4N32, each input typically connects to the LED side of the optoisolator, allowing the input signal to control the LED, which is isolated from the CPU. The output side, which consists of a phototransistor, interfaces with the CPU by switching based on the input signal's LED activation. This configuration provides electrical isolation between the CPU and the input signals, protecting the CPU from voltage spikes or noise. Overall, the input signal triggers the optoisolator, and the output signal relays this information to the CPU.
