Current input isolator providing one isolated power supply to 2-wire and 3-wire transmitters, while detecting the current signal output by the transmitter and transmitting it via isolated passive output; also supports bidirectional HART digital signal transmission. Requires independent power supply, with three-port isolation between input, output and power supply.
