Current input isolator that provides one isolated power supply to 2-wire and 3-wire transmitters while detecting the current signal output by the transmitter, which is then isolated and transmitted; it also supports bidirectional transmission of HART digital signals. It features fast response, low temperature drift and high accuracy. It requires an independent power supply, with three-port isolation between input, output and power supply.
