In this animated object, learners examine how to wire field devices to a PLC sinking input module.
Waveforms of an SCR Circuit
By Terry Bartelt
Learners view waveforms at various locations of an SCR circuit controlling the intensity a light bulb. The waveforms are shown when the light is dim, at medium brightness, and at full brightness. A brief quiz completes the activity.
Single-Phase Motors: Introduction to Phase-Splitting
By Terry Bartelt, Terry Fleischman
Learners will understand how the interaction of the armature magnetic field and the rotating stator field cause the rotor of a single-phase AC motor to turn.
Incremental Encoder Quadrature Modes
Learners study the method of using more than one track and quadrature modes to improve the resolution of an optical encoder. A brief quiz completes the activity.
Statics: Force Systems
By Steve Whitmoyer
Learners read an introduction to the four basic types of force systems for a statically determinate condition.
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.
Clock Pulse Triggering of Flip-Flops
This learning object shows the symbols used to represent the type of pulse required at the clock input to activate flip-flops.
Digital Circuit Devices
The two types of digital devices, logic gates and flip-flops, and the types of basic operations they perform are presented.
You'll focus on terminology related to designing a hypothetical program.
Answer given questions on Data and programs.
Computer Input Devices
This game focuses on basic input devices common in computer systems.
