Working Principles

The SI8901D-A01-GS utilizes optocoupler technology to achieve signal isolation. It consists of an input side and an output side, which are electrically isolated from each other. The input signal is converted into light by an LED on the input side, and this light is then detected by a photodiode on the output side, which generates the corresponding output signal. This optical isolation ensures that there is no direct electrical connection between the input and output sides, providing protection against voltage spikes and noise.
