Notice:
1. If the power supply E in the high voltage area and the low voltage area are connected to the same ground, the G in this module only needs to be connected to one ground.
2. The conversion module is equivalent to a straight line, each port is one-to-one, but the voltages on the two sides are different, thus realizing the communication between different levels.
3. This module cannot be used as a voltage stabilizer or a transformer. It can only be used for I0 port, small current communication between levels.
