LW3048 Isolated RS-485 Interface with Field Device Power Supply

The LW3048 is an isolated RS-485 interface for bidirectional half-duplex communication between field devices and PLC/DCS systems. It provides electrical isolation between the RS-485 interface, field-device power supply and system power, while also supplying isolated power to connected field equipment. Communication speeds up to 115.2 kbps and transmission distances up to 1200 m are supported.
