Learners examine the functions of the three types of memory used by an Allen-Bradley SLC-500 programmable logic controller: the Executive ROM, Scratch Pad, and Processor File.
This animated guide presents an FAA map and aerial photos showing various areas of interest to student pilots enrolled in flight training at FVTC Aviation at Wittman Regional Airport in Oshkosh, WI. The airport is the site of the annual Experimental Aircraft Association's AirVenture Oshkosh. This object has sound.
Learners examine OSHA's guidelines of what to include in a bloodborne pathogen exposure control plan for persons who work in general industry, health care, emergency medical services, law enforcement, education, recreation industries, or other occupations in which there is a potential for exposure to blood, blood products, bodily fluids, or human tissues.
In this interactive object, learners follow the steps required for the Ziegler-Nichols Continuous Cycling method. The process identification procedure is performed, calculations are made, and the proper PID values are programmed into the controller.
Learners view an animated presentation showing how the pH level of a cleaning solution is controlled in a closed-loop system in a manufacturing setting. A quiz completes the activity.
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.
In this animated object, learners view a race of two boats as an example of how the derivative function of a PID controller shortens the time duration of an operation.
In this animated object, learners examine the design of a ladder circuit that provides manual control to a water pumping system. Students also study modifications to the circuit as the complexity of the system increases.
In this animated activity, learners examine how an adjustable pressure-reducing valve can produce a pressure that is lower at its output than at its input.
In this colorful and animated activity, learners study the operation of a needle valve and the operation of the needle valve with a check valve. A brief quiz completes the activity.
