LW3711 Loop-Powered 4¨C20 mA Signal Isolator with HART Pass-Through

The LW3711 is a loop-powered transmitter power supply and signal isolator for 2-wire transmitters. It supplies isolated power to the field transmitter while transmitting its 4¨C20 mA measurement signal to the control system. No separate operating power supply is required, and optional HART communication allows bidirectional digital communication over the current loop.
