Learners observe how to cascade PLC counters to extend the maximum count of one counter.
How to Reset a Counter
By Terry Bartelt, Tom Yapp
In this animated object, learners examine the proper way to reset a counter instruction in a programmable controller.
The Timing Functions of Optical Sensors
By Terry Bartelt
In this animated object, learners examine the switch settings for the on-delay, off-delay, and one-shot timing functions of an optical sensor. A brief quiz completes the activity.
Excel: Determining the Square Root of a Complex Number
By Patrick Hoppe
Learners view the steps for determining the square root of a complex number in Excel.
Identifying the Number of Significant Digits
By Ron Wallberg
Learners will identify the number of significant digits in practice problems.
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.
