Is ISO7741 support for RS485 communication Line (A,B) Isolation.?

We need to Isolate the RS485 Communication Lines A & B HMI communication (RJ45 Connector ) in  Interface PCB.  to RS485 Distribution board 

Problem we are facing the RS485 module we used (CS1030) &  transceiver IC Failure in Interface PCB.

So we thought to add Isolation  or Protection in Distribution Board.

Suggest me the Simple Possible Solution. with readymade IC Solution / any protection circuit.
