Sequencer Output Instruction for the SLC-500 PLC
By Craig Hemken
Learners examine the fundamental concepts of sequencer output instruction. A simulated example shows a sequencer in operation.
Sinking/Sourcing Output Module
By Terry Bartelt
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.
Functions of Hydraulic Oil
Learners observe the four functions of oil in a hydraulic system.
Pressure-Controlled Sequencing Circuit
This animated lesson shows how a pressure switch connected in a ladder circuit causes the cylinder of a hydraulic circuit to extend and retract.
The learner will gain an understanding of the modes of axis movement for successful robot programming.
By John Casey, Terry Bartelt
In this animated learning object, learners examine how an ultrasonic flowmeter measures the flow of liquids through a pipe using ultrasonic sound waves. A short quiz completes the activity.
Introduction to Class 2 Levers
By James Bourassa, John Rosz
In this interactive object, students view an animated depiction of Class 2 levers. A matching quiz completes the activity.
The Vortex Flowmeter
Learners view an animation showing the operation of a Vortex flowmeter that is used to measure flow in a process control system.
Learners observe how an optical pyrometer is used to take temperature measurements without making physical contact with the object being measured.
Ziegler-Nichols Continuous Cycling Tuning Calculations
Learners examine the formulas that are used to determine the proper PID values to be entered into a controller using the Ziegler-Nichols Continuous Cycling Tuning Method.
Pressure Measurements in Inches of Water Column
Learners read how inches of water column is used as a unit of pressure measurement. Practical applications and a conversion formula to psi are included.
Phase-Splitting of Single-Phase Motors
By Terry Bartelt, Terry Fleischman
The learner will understand the two methods used to create a phase shift in current between two windings.
Electrical Generator Basics
In this animated activity, learners examine how a voltage is induced into a conductor when the conductor cuts across magnetic flux lines. They also view the four factors that determine how much voltage is generated. A brief quiz completes the learning object.
Proportional Control Amplifier
Learners examine the operation of a proportional control amplifier and the two ways that it is programmed using proportional gain or proportional band. A brief quiz completes the activity.
