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.
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.
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.
