The 4- to 20-mA current loop is ubiquitous in the world of controls in manufacturing plants. Discrete logic, microprocessors, and microcontrollers easily cover the digital portions of control schemes, ...
Loop-powered transmitters have progressed from purely analog signal conditioners to highly flexible smart transmitters, but the chosen design approach still depends on a system’s performance, ...
In electronic systems, wires and cables provide intentional circuit paths for power or signal currents to move from a source to a load and then return to the source. These current paths have the ...
