Hydraulic Color Code Circuit Example
By Terry Bartelt
In this animated and interactive object, learners use a color code to understand the operations of a hydraulic circuit. A brief quiz completes the activity.
Hydraulic Pump Action
By Terry Bartelt, Stephen Schneider
Learners examine how fluid enters the inlet of a hydraulic pump because of atmospheric pressure and how pressure is created at the pump’s outlet. This object includes audio.
Types of Pneumatic Compressors
Learners examine the operation of positive and non-positive displacement compressors used in pneumatic systems.
The Shunt Motor Open Field
In this animated object, learners observe the changes inside the DC shunt motor that could cause the motor to break apart when its field coil opens. A short quiz completes the activity.
Automatic PLC Counting
By Terry Bartelt, Tom Yapp
Learners study an animated PLC counting operation and examine how the count is automatically reset.
Thru-Beam Photoelectric Sensors
This animated lesson shows the operation and characteristics of thru-beam optical sensors.
Overflow and Underflow for Signed Binary Numbers
By John Casey, Terry Bartelt, Terry Fleischman
Learners examine the occurrence of overflow and underflow conditions in a programmable logic controller. It is recommended that users view the learning object “Signed Binary Numbers” in advance of this object.
Digital Position Control
In this animated object, learners examine a closed-loop feedback system that uses digital circuits to control the position of a gear rack.
One-Shot PLC Operation
Learners view an animation showing the one-shot operation of a programmable logic controller.
Elements of a Closed-Loop System
By Terry Bartelt, Terry Fleischman
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.
P&ID General Instrument Symbols
Learners study the types of symbols used on a P&ID diagram to indicate instruments. A quiz completes the activity.
Hydraulic Brake Valves
The operation of a hydraulic brake valve, including the internal components, is presented using animations.
Normally Open vs. Normally Closed Pressure Control Valves
In this animated activity, learners examine the operation of normally open and normally closed valves used in hydraulics. A brief quiz completes the learning object.
Dynamic Braking Circuits
In this animated activity, learners examine the operation of a dynamic braking circuit used to quickly stop a motor.
PLC Output Modules
The learner will understand the operation and configuration of various types of PLC output modules and how they're used.
Learners view an animation of a counterbalance valve in operation and examine the valve’s internal structure.
In this animated object, learners examine different types of pneumatic actuators, cylinders, and motors.
Motor Control Circuits
Learners examine an electric motor control circuit that uses a motor starter module. This activity has audio content.
The Closed-Loop Velocity Servo System
In this animated object, learners examine the operation of a closed-loop system that maintains the speed of a conveyer belt as heavy boxes are placed or removed.
Hall-Effect Sensor Application
Learners view practical examples of how a Hall-effect sensor is used.
Volts per Hertz Ratio in AC Drives
Learners view an animated explanation of why an adjustment of the output voltage by an AC drive is required to maintain a constant torque as the frequency is varied.
Converting Between Gray and Binary Codes
Learners follow steps to convert numbers from Gray code to binary code. They then view steps to change binary values to Gray code numbers.
Endothermic vs. Exothermic Reactions
In this animated object, learners examine how the heating or cooling steps in a manufacturing process work to control a chemical reaction.
Photoelectric Reciprocation Circuits
This animated lesson shows how a photoelectric sensor, connected to a ladder circuit, causes the cylinder of a hydraulic circuit to extend and retract.
