Learners examine the counter-reset function of a programmable controller and how it is used.
By Terry Bartelt
In this animated object, learners examine the signals produced by sourcing and sinking two-wire sensors. A brief quiz completes the activity.
Designing a Ladder Diagram
In this animated object, learners examine the design of a ladder circuit that provides manual control to a water pumping system. Students also study modifications to the circuit as the complexity of the system increases.
Converting Rotational Velocity to Linear Velocity
By James Bourassa, John Rosz
In this animated object, students view an example of how to convert rotational velocity to linear velocity. They then work practice problems.
Pneumatic Directional Control Valves (Screencast)
In this animated object, learners examine the operation of two-way, three-way, and four-way directional control valves used in pneumatic systems.
An Inductor Opposing a Current Change
Learners read how an inductor opposes a current change when it begins to energize and when it begins to de-energize. A short quiz completes the activity.
The schematic symbols of logic gates used in digital circuits are shown.
In this learning activity you'll explore the operation of frequency division using several different types of counters.
Logic State Signals
In this learning activity you'll identify the voltage levels produced or recognized by digital logic devices as valid or invalid logic state signals.
Instructions on how to use and construct a truth table for digital devices are provided.
You'll focus on terminology related to designing a hypothetical program.
