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.

You can put the ETH Adapter CN on your desk or install it on the rail of control cabinet.It has the

mounting bracket accessory.User can self-make an Aluminum board with thickness 1.5mm～

2.5mm,then install the adapter on the S7-300/400PLC rail or 35MM standard rail.
