Isolated RS-485

Analog Devices offers a wide range of iCoupler® isolated RS-485 transceivers to suit many applications. These galvanically isolated RS-485/RS-422 transceivers are available in full duplex and half duplex for use in markets ranging from Motor Control to Industrial Automation, and Process Controls. These parts meet the RS-485 specification for a true multipoint communications network supporting 32 nodes on a single (2-wire) bus, with some able to modify the input impedance to allow up to 8× more nodes all with up to 5kVrms insulation ratings.
