An input loop-powered isolator is powered from the 4-wire transmitter in the ï¬ eld. The transmitterâs 4-20mA output and its compliance voltage must power the isolator electronics and the isolatorâs output. Because loop-power is limited, the isolatorâs output load is held to 250 ohms. The receiverâs input impedance can be anywhere from 0-250 ohms, and it should be a ï¬ xed load.
