In this interactive object, learners view a practical application of a PLC Timer-On function.
The Half-Wave Rectifier
By Terry Bartelt
In this animated learning object, students read about the operation of a half-wave rectifier.
Transistor DC Analysis Practice Problems: Circuit #3
By Patrick Hoppe
Learners analyze an emitter-biased npn transistor circuit. A "help" screen is available.
Parallel RL Circuit Vector and Circuit Analyzer
By James Bourassa, John Rosz
Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
The learner views animation showing how a DC motor is wired and its operational characteristics. A short quiz completes the activity.
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.
In this animated object, learners examine how PLC up/down-counters are used to control an automated parking lot gate.
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.
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.
PLC Output Modules
By Terry Bartelt, Terry Fleischman
The learner will understand the operation and configuration of various types of PLC output modules and how they're used.
You'll focus on terminology related to designing a hypothetical program.
