Photoelectric Reciprocation Circuits
By Terry Bartelt
This animated lesson shows how a photoelectric sensor, connected to a ladder circuit, causes the cylinder of a hydraulic circuit to extend and retract.
Physics Concepts in Hydraulics
In this animated activity, learners view the following physics concepts in action: force, friction, horsepower, work, power, inefficiency, resistance, inertia, and energy.
Single-Cycle Reciprocation Circuit
In this animated lesson, the learner examines how a ladder circuit causes the cylinder of a hydraulic circuit to make a single extension and retraction.
Motor Speed Control
Learners examine the speed control circuits in a DC variable speed drive that cause the RPM of a motor to vary. This activity has audio content.
A Timer-On Application
In this interactive object, learners view a practical application of a PLC Timer-On function.
Visual Logic Basic Programming: Using Flow Charts
By Jason Vosters
In this learning activity you'll understand what flow charts are and how they're used to create computer programs.
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.
