Learners examine how a PLC Timer-Off instruction is used in the operation of an automotive paint booth.
Manual Control of a Reciprocation Circuit
By Terry Bartelt
This animated lesson shows how pushing a start or stop button on a ladder circuit causes the cylinder of a hydraulic circuit to extend and retract.
Calibrating an Opposed Optical Sensor
In this animated and interactive object, learners follow three steps to calibrate an opposed optical sensor. They consider horizontal alignment, the sensitivity setting, and having an effective beam.
Discharging Time Constants of an RC Circuit
In this animated object, learners examine how current, voltage and the discharging capacitor of a series RC changes during 5 time constants. A brief quiz completes the activity.
Mechanical Advantage (Screencast)
By James Bourassa, John Rosz
Learners apply lever ratios to calculate the mechanical advantage in basic mechanisms.
By Rosie Bunnow
Learners practice revising poorly written directions by applying criteria for giving directions.
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.
