Learners view an animation showing the one-shot operation of a programmable logic controller.
Reversing the Rotation of DC Motors
By Terry Bartelt, Terry Fleischman
Learners view animations showing how to change the connections to cause a DC motor to reverse its rotation. A short quiz completes the activity.
Total Impedance of a Series Circuit Using Complex Numbers
By Patrick Hoppe
Students view several examples of how to determine the total impedance of a series circuit. The "j" term is used in all of the calculations.
The MOD 10 Counter
The technique for designing a MOD 10 counter is introduced. Asynchronous inputs of a JK flip-flop are used to clear the counter.
Hall-Effect Sensor Application
By Terry Bartelt
Learners view practical examples of how a Hall-effect sensor is used.
The schematic symbols of logic gates used in digital circuits are shown.
Instructions on how to use and construct a truth table for digital devices are provided.
The Logic Gates
Students read information about basic logic gates including the gates' names, symbols, Boolean expressions, pronunciations, and truth tables. They then complete a matching exercise.
In this learning activity you'll review the operation of an Exclusive-NOR gate by using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.
Sequencer Output Instruction for the SLC-500 PLC
By Craig Hemken
Learners examine the fundamental concepts of sequencer output instruction. A simulated example shows a sequencer in operation.
You'll focus on terminology related to designing a hypothetical program.
