Learners study an animated block diagram that describes the function of each element in a closed-loop system used in industrial automation.
Understanding and Writing Pseudocode: The Basics
By Jason Vosters
In this activity you'll explore how flowchart programs can be converted into pseudocode programming.
Hydraulic Color Code Drill
By John Rosz, Terry Bartelt
This interactive learning object is designed to help learners memorize the color code used on some hydraulic schematic diagrams. Learners quiz themselves using electronic flashcards.
PLC Sinking Input Modules
In this animated object, learners examine how to wire field devices to a PLC sinking input module.
The Dynamic Response of a Closed-Loop System
Learners examine the factors that contribute to the delays in the response time throughout a closed-loop system.
PLC Timer Instructions
Learners examine the animated Timer-On Delay instruction and the Timer-Off Delay instruction of a PLC timer. A brief quiz completes the activity.
The Timer 3-Word Element
Learners study the descriptions of the three words in a PLC timer: EN, DN, and TT. They then test their knowledge in a brief quiz.
Forward/Reverse Ladder Circuits
In this animated object, learners study the operation of a ladder circuit that controls the rotational direction of a DC motor.
Basic Elements of a Plastics Extruder
By Craig Hemken
In this animated object, learners examine the parts of a plastics extruder. A quiz completes the activity.
Displacement and Velocity Ratios
By James Bourassa, John Rosz
In this animated object, learners examine formulas for displacement and velocity ratios. They also view examples and calculate velocity and the velocity ratio.
The Three-Phase Motor Stator Field
In this animated activity, learners study how stator poles create a rotating field in a three-phase AC motor as a three-phase AC voltage is applied.
On-Off Control of a Feedback System
Learners examine the operation of the on-off control mode using a home heating example. A short quiz completes the activity.
The IR Comp Network
In this animated activity, learners examine the circuitry in a DC variable speed drive that keeps the motor running at a constant speed as the load varies.
In this animated activity, learners examine how the speed of a motor may change if the voltage from the power source fluctuates due to power line irregularities. This lesson has audio content.
Inductive Proximity Sensor Target Considerations
Learners consider the factors that determine how well an inductive proximity sensor can detect an object. Those factors are size, position, and the material from which the target is made. A brief quiz completes the activity.
Pneumatic Air Leaks
By Terry Bartelt, Stephen Schneider
In this animated object, learners examine the causes of air leaks and read how to repair them. The object includes audio.
Learners view an animation showing how the volume of a given quantity of gas varies directly with its temperature.
Direct-Operated, Pressure-Reducing Valves
By Terry Bartelt, Doyle Davis
In this animated activity, learners examine how an adjustable pressure-reducing valve can produce a pressure that is lower at its output than at its input.
Continuous-Cycle Reciprocation Circuit
This animated lesson shows how a ladder circuit causes the cylinder of a hydraulic circuit to continuously extend and retract after a Start button has been pressed.
Slow PLC Scan Time
In this animated object, learners study the problems that develop if the scan time of a PLC is too slow.
The Hydraulic Cylinder
In this animated and interactive object, learners examine the basic parts and the linear movement of a hydraulic cylinder. A brief quiz completes the activity.
Pressure-Controlled Sequencing Circuit
This animated lesson shows how a pressure switch connected in a ladder circuit causes the cylinder of a hydraulic circuit to extend and retract.
Integral Reset Setting
Learners study animations showing the integral function of a closed-loop control system and the difference between the two types of integral controller settings, reset rate and reset time. A short quiz completes the activity.
