A relay logic circuit is a schematic diagram that displays various components, their connections, inputs, and outputs in a specific way. In relay logic circuits, contacts NO and NC are used to indicate normally open or normally closed relay circuits. It contains two vertical lines, one on the far left and the other on the far right. These vertical lines are called orbits. The leftmost power rail is at the power voltage potential and serves as the input power rail. The rightmost power rail is at zero potential and serves as the output power rail.
