Use Low-Impedance Bridges on 4-20mA Current Loop

Texas Instruments

Published Date: 09/27/2000

Description

If you need more transducer excitation current than is available on a standard 4-20mA 2-wire current loop consider a 3-wire transmitter. A 2-wire 4-20mA transmitter uses the same two wires for signal and power. Part of the 4mA minimum loop current is used to power the transmitter circuitry. The remaining current can be used for transducer excitation. In some applications even the entire 4mA is no
