Learners observe how to cascade PLC counters to extend the maximum count of one counter.
Kirchhoff's Current Law
By Tim Tewalt, Patrick Hoppe
Learners observe how branch current values in parallel circuits are affected when different values are used. They test their knowledge by answering 11 review questions.
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.
By Terry Bartelt
In this animated object, learners examine how PLC up/down-counters are used to control an automated parking lot gate.
P&ID Tag Numbers
Learners study the types of information letters and numbers placed inside general piping and instrumentation diagram symbols.
An Inductor Opposing a Current Change
Learners read how an inductor opposes a current change when it begins to energize and when it begins to de-energize. A short quiz completes the activity.
The schematic symbols of logic gates used in digital circuits are shown.
In this learning activity you'll explore the operation of frequency division using several different types of counters.
Instructions on how to use and construct a truth table for digital devices are provided.
The Logic Gates
By Patrick Hoppe
Students read information about basic logic gates including the gates' names, symbols, Boolean expressions, pronunciations, and truth tables. They then complete a matching exercise.
You'll focus on terminology related to designing a hypothetical program.
