Learners view an animation showing the one-shot operation of a programmable logic controller.
The RC Time Constant
By Patrick Hoppe
Learners examine the concept of the RC time constant. The instantaneous voltage across the capacitor is calculated.
By Terry Bartelt
In this animated object, learners examine how PLC up/down-counters are used to control an automated parking lot gate.
An Impedance Matching Application
Learners consider why an impedance matching transformer is needed to connect an antenna to a television.
Radiation Quantities and Units
PLAY BALL using your knowledge of radiation quantities and units.
Selector Switch Labeling
In this animated object, learners examine the method of interpreting the truth tables for two-position and three-position selector switches on ladder logic circuit diagrams.
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.
Basic DC Electrical Motor Construction
Learners examine the internal parts of a DC electrical motor and then text their knowledge in a drag-and-drop exercise.
Ladder Logic Schematic Symbol Flashcards
By John Rosz, Terry Fleischman
This interactive object is designed to help learners memorize the schematic symbols used in ladder logic diagrams. Learners quiz themselves using electronic flashcards.
You'll focus on terminology related to designing a hypothetical program.
