Fully Isolated Transceiver Solutions for RS-485

Analog Devices Inc. and HALO Electronics partner to offer fully isolated transceiver solutions for RS-485/Profibus high-speed industrial applications. ADI RS-485/Profibus half-duplex DP transceivers provide galvanic isolation (2750V or 5000V), improving communications by breaking ground loops. This reduces noise caused by significant differences in ground potential between ports.
