Working Principles

The FIN1002M5 utilizes transformer-based isolation technology to provide galvanic isolation between the input and output sides. It employs a combination of transformers, capacitors, and logic circuitry to ensure signal integrity and voltage level shifting. The input signal is coupled through a transformer, which isolates it from the output side. The isolated signal is then shifted to the desired voltage level using logic circuitry. The output signal is then transmitted through another transformer to maintain isolation.
