Nice Electrical Ladder Diagram
Circuits are connected as horizontal lines i e the rungs of the ladder between these two verticals.
Electrical ladder diagram. The two vertical lines are called rails and attach to opposite poles of a power supply usually 120 volts ac. These diagrams represent the interconnection of field devices in such a way that the activation or turning on of one device will turn on another device according to a predetermined sequence of events. Ladder diagrams sometimes called ladder logic are a type of electrical notation and symbology frequently used to illustrate how electromechanical switches and relays are interconnected.
A wiring diagram is an electrical print that shows connections of all components in a piece of equipment a schematic diagram is a type of drawing that illustrates the electrical connections and functions of specific circuit arrangements with graphic symbols a ladder diagram is a diagram that explains the logic of the electrical circuit or system using standard nema or iec symbols. The ladder diagram consists of two vertical lines representing the power rails.
