P&ID Tag Numbers
By Terry Bartelt
Learners study the types of information letters and numbers placed inside general piping and instrumentation diagram symbols.
In this animated activity, learners examine the three main segments of a hydraulic system: power supply, control, and output. A brief quiz completes the learning object.
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.
Hydraulic System Pressure
In this animated activity, learners observe how pressure values throughout a hydraulic system are developed based on pump pressure and the size of the load.
In this animated activity, learners study how the magnetic field of an armature can distort the DC motor's main magnetic field. A brief quiz completes the object.
Fundamentals of a DC Motor
Learners study the interaction between the conductors of the stator and the armature inside a DC motor, which causes the shaft to rotate. A short quiz completes the activity.
Learners study the method of cascading two or more PLC timers to extend their time capacity.
Pressure-Reducing Valve Application
By Terry Bartelt, Stephen Schneider
In this animated activity, a drill-and-clamp machine is used to show an application of a pressure-reducing valve. Recommendations on how to properly make pressure adjustments are also provided.
Hydraulic Cylinder Speed
In this interactive and animated object, learners examine why the piston of a hydraulic cylinder extends slower than it retracts. A brief quiz completes the activity.
Hydraulic Schematic Symbol Flashcards
By John Rosz
This interactive object is designed to help learners memorize schematic symbols used in hydraulic diagrams. Learners quiz themselves using electronic flashcards.
Learners observe how to cascade PLC counters to extend the maximum count of one counter.
Identifying Lever Classes
By James Bourassa
In this interactive object, learners read an introduction to Class 1, Class 2, and Class 3 levers and then take a quiz.
What Is Torque?
Learners read a description of torque and study the factors that cause its magnitude to change. A brief quiz completes the activity.
PLC Shift Registers
By Terry Bartelt, Tom Yapp
In this animated activity, learners study how a PLC performs a shift operation. The learning object covers data movement, data entry, PLC wiring, PLC shift register introductions, and programming for a paint can operation.
Reaction Curve Tuning Example
Learners perform the steps required for the Ziegler-Nichols Reaction Curve Tuning Method. The process identification procedure is performed, calculations are made, and the proper PID values are programmed into the controller.
The Elementary AC Generator
Learners view animations showing the operation of the internal parts of an AC generator. A short quiz completes the activity.
Three Phase Wye Transformer Calculations
In this interactive object, learners follow steps to find phase voltages in a partial three-phase power distribution circuit.
In this animated object, learners study how the internal parts of an AC synchronous motor interact with magnetic fields to cause rotation. A short quiz completes the activity.
Armature Action of AC Motors
In this animated object, learners study the rotation of the magnetic stator field of an AC motor and how it interacts with the armature to cause rotation. A short quiz completes the activity.
Pneumatic Schematic Symbol Flashcards
This interactive object is designed to help learners memorize schematic symbols used in pneumatic diagrams. Learners quiz themselves using electronic flashcards.
Comparing Electronic and Hydraulic Components
Learners read about the similarities of electronic and hydraulic components and then match the schematic symbols in a drag-and-drop exercise.
The Induction Motor Slip
In this animated object, learners examine how the rotation of an induction AC motor's armature slips behind the synchronous rotational speed of the stator's field to create magnetic fields. These fields interact and produce torque. A quiz completes the activity.
Analog Position Control
In this animated object, learners examine an analog closed-loop feedback system that uses potentiometers to control the position of a gear rack.
Comparing Hydraulics and Pneumatics
Learners examine the differences and similarities between hydraulic and pneumatic systems.
A Timer-Off Application
Learners examine how a PLC Timer-Off instruction is used in the operation of an automotive paint booth.
