Learners study the method of cascading two or more PLC timers to extend their time capacity.
The Vortex Flowmeter
By Terry Bartelt
Learners view an animation showing the operation of a Vortex flowmeter that is used to measure flow in a process control system.
Value-Added vs. Non-Value-Added Activities
By Terry Bartelt, Terry Fleischman
In this interactive object, learners read a description of value-added and non-value-added activities and then place various work duties into these two categories.
Motor Starter Protection
Learners examine the ways in which a motor starter circuit is protected by a main circuit breaker and overload heaters when there is excessive current.
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.
The schematic symbols of logic gates used in digital circuits are shown.
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.
Digital Circuit Devices
The two types of digital devices, logic gates and flip-flops, and the types of basic operations they perform are presented.
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.
