Learners examine the labeling scheme used in ladder logic diagrams to identify components, wires, rungs, and rails. This activity includes self-check questions.

Explore how to prevent injuries caused by falling from ladders or elevated heights by looking at the parts of a ladder, ladder safety rules, and personal fall protection systems.

Learners study the operation of a ladder circuit in which coils on one rung control contacts in other rungs.

Learners examine how a ladder logic circuit becomes latched when a normally open pushbutton is momentarily pressed.

In this animated object, learners study the operation of a ladder circuit that controls the rotational direction of a DC motor.

This interactive object is designed to help learners memorize the schematic symbols used in ladder logic diagrams. Learners quiz themselves using electronic flashcards.
