Why the 24V power,RJ45 port and RS485 three parties all need to be isolated?That's because the
7 pin and 2 pin(output 24VDC power) and RS485 interface(DB9F socket 3、4、5、6、8、9pin) on
the PLC PROFIBUS socket are isolated,if the adapter is not isolated,it will damage the PLC
isolation system,then damage the PLC or cause interference.
