Learners use the National Electrical Code to determine the size of a motor overload protection device.

The two types of digital devices, logic gates and flip-flops, and the types of basic operations they perform are presented.

In this document you'll review drill press work-holding devices.

In this animated object, learners view the operation of an open-collector inverter with and without a pull-up resistor.

Learners study the fundamental operation of a triac, particularly how it is turned on and off. A brief quiz completes the activity.

Learners examine how a linear displacement transducer is used to measure the linear position of a physical object. Animations show the sequential steps of the entire operation.

In this animated object, learners examine the fundamental operation of a diac including how it is turned on and turned off. A brief quiz completes the activity.

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.

This project gives steps to complete the activity.

Electronic WorkBench has a virtual instrument called "The Bode Plotter." Students view the proper set-up and use of this device.

Learners examine the sourcing and sinking of conventional current at a PLC output module and the type of field device to which it is connected. This interactive learning object includes six quiz questions.

In this animated and interactive object, learners use a memory device to identify NPN and PNP transistors. Learners also examine how much the transistors turn on when the voltage applied to the base is varied.

Learners examine the conventional current flow at a PLC input module, along with the field devices connected to it. This interactive object includes quiz questions and feedback.

Learners view examples of devices that prevent mistakes from occurring.

The student reviews milling machine work-holding devices.

Instructions on how to interpret state indicator symbols for input and output terminals of digital devices is presented.

Instructions on how to use and construct a truth table for digital devices are provided.

In this interactive and animated object, learners study how to wire field devices to a PLC sourcing input module. A brief quiz completes the activity.

In this animated activity, the learner examines how a 74150 IC multiplexer and a 74154 IC demultiplexer work together when their data select lines are connected to the same input devices.

In this interaction the student is presented with 10 questions on indirect measuring devices and their uses.
