Industrial Controllers Unit

The Industrial Controllers Unit, is based on a modular design structure whose functionality is divided into different modules toallow the student a better understanding of the unit. The modules included in the unit are: industrial controller, digital voltmeter, set pointgenerator, system simulator and communication module.
