This animated lesson shows the operation of timer-on and timer-off delay relays used in ladder circuit operate.
The Impact of Batch Size Reduction
By Kaye Krueger
In this animated object, learners examine what happens to lead and cycle times when the batch size is reduced.
Work and Power (Screencast)
By James Bourassa, John Rosz
Learners examine the formulas for calculating work in ft-lb units and power in ft-lb/min. units.
High-Low Speed Drive Adjustments
By Terry Bartelt
Learners examine the circuitry in a DC variable speed drive that prevents the motor from running at 0 rpm or at maximum speed under certain conditions.
Inductive Proximity Sensors
Learners examine the operation of an inductive proximity sensor in this animated object. A brief quiz completes the activity.
In this animated lesson, students view the operation of an electromechanical relay. A brief quiz concludes the activity.
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.
You'll focus on terminology related to designing a hypothetical program.
