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, ...
Current sources are widely used in industrial control systems to transport analog process signals over long distances, but they are less widely used than voltage sources. This post loosely reviews the ...
In a previous Idea for Design, Anshi Chen outlined a method for analyzing electrical circuits using Kirchhoff’s current law (KCL) in a novel way that allowed designers to simply write down the needed ...
