Learners observe how to cascade PLC counters to extend the maximum count of one counter.
Excel: Entering a Complex Number
By Patrick Hoppe
Learners examine the complex number function to convert real and imaginary coefficients into a complex number.
Voltmeter Circuit Connections
By Terry Bartelt
Students read a step-by-step approach on how to connect a voltmeter to a circuit when making a measurement.
Identifying Lever Classes
By James Bourassa
In this interactive object, learners read an introduction to Class 1, Class 2, and Class 3 levers and then take a quiz.
Standard Transmission Signals
Learners examine animations of the most common transmission signals used in automated systems, such as 4 mA to 20 mA, 3 psi to 15 psi, and 0 to 10 volts. A brief quiz completes the activity.
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.
Logic State Signals
In this learning activity you'll identify the voltage levels produced or recognized by digital logic devices as valid or invalid logic state signals.
Instructions on how to use and construct a truth table for digital devices are provided.
You'll focus on terminology related to designing a hypothetical program.
