LW3148 Intrinsically Safe Isolated RS-485 Interface with Field Device Power Supply

The LW3148 provides bidirectional half-duplex RS-485 communication between safe-area PLC/DCS systems and hazardous-area field devices. It electrically isolates the RS-485 communication, power and field-device circuits and can provide isolated power to the connected field equipment. It supports transmission distances up to 1200 m and baud rates up to 115.2 kbps.
