In this animated activity, learners examine the three main segments of a hydraulic system: power supply, control, and output. A brief quiz completes the learning object.
In this animated object, learners examine the operation of a thermal flowmeter used in process control applications. A brief quiz completes the activity.
In this animated activity, students view the plastic pellets in a profile extrusion machine being melted as the temperature of the heating elements is elevated by a time proportioning control system.
Learners examine the two methods used by programmable logic controllers to perform a counting operation using addition or counter instructions. A brief quiz completes the activity.
In this animated object, learners examine the operation of up-counters and down-counters for a programmable controller. A brief quiz completes the activity.
Learners use this interactive and animated object to examine the use of binary numbers in a programmable logic controller. A brief quiz completes the activity.
Learners perform the steps required for the Ziegler-Nichols Reaction Curve Tuning Method. The process identification procedure is performed, calculations are made, and the proper PID values are programmed into the controller.
In this animated object, learners examine three data compare instructions used by programmable logic controllers (PLCs). A practical application to show how these instructions are used in an industrial setting is provided.
Op Amp Fundamentals: The Transconductance Amplifier
Students read an introduction to the transconductance amplifier. They also view formulas for voltage-to-current conversion, closed-loop input, and output impedance. An example of how R1 controls the conversion factor is given.
Learners examine the occurrence of overflow and underflow conditions in a programmable logic controller. It is recommended that users view the learning object “Signed Binary Numbers” in advance of this object.
