Transmitters are available with either floating outputs (typically used in loop-powered applications) or with single-ended outputs (typically used in locally-powered applications). This application ...

This reference design shows how to develop a high-performance, high-voltage 2- or 3-wire 4–20mA current-loop transmitter suitable for industrial process control and ...

Galvanically (that is, optically or electromagnetically) isolated 4- to 20-mA current loops offer robust noise immunity and tolerate long cable runs. These advantages, combined with simple unshielded ...

To reduce noise and voltage drops in analog voltage signals, the market place has adopted an analog current (4-20mA) output as its sensor signaling standard. A very robust signal, 4-20mA current ...
