Professional Insights
Industrial communication isolation requires attention to network topology and grounding. For RS-485, proper termination at both ends is critical - use 120Ω resistors and keep stubs short. For CAN, split termination provides better EMI performance. Always ensure isolated power supplies have adequate decoupling. The high CMTI of Chipanalog products ensures reliable operation even with motor drives on the same power system.
