RT 451 - RT 455

The series RT 451 – RT 455 is constructed entirely from industrial components in order to teach control engineering in a practical manner. The use of smart sensors lays the foundations for Industry 4.0 applications.

For operation and control, all the trainers include an integrated PLC and touch screen.

A separate trainer is available for all important controlled variables in process engineering. The control loops are clearly arranged. All associated components can be easily identified visually.


Learning objectives

  • design and function of different controls

  • investigate the properties of open and closed loops

  • investigate disturbance and reference variable response

  • familiarisation with industrial control engineering components

  • learn about the features of smart sensors

  • extended data transmission e.g. configuration data, statistical data on system status, events

  • digital interfaces for the connection to the system

Integrated PLC: Siemens S7-1200
