Ladder Logic

Ladder Logic

Created by Tony R. Kuphaldt, with help from contributor Roger Hollingsworth, this chapter of All About Circuit's fourth volume on Digital circuits describes the logic behind them. The chapter is divided into six sections: "Ladder" diagrams, Digital logic functions, Permissive and interlock circuits, Motor control circuits, Fail-safe design, and Programmable logic controllers. Each section has clear illustrations and a concise, bulleted review of what was covered at the end. There is also a link to the All About Circuits forums, where contributors and other visitors discuss the material presented. This is an excellent resource for educators in physics and electronic engineering classrooms to introduce lessons or units on digital circuits.
