The instrumentation signals vary within a range of 4mA to 20mA, depending on the value of ... supply and the process input and/or output signal. Isolators, like most other transmitters, come in 2- and ...

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 ...
