Description

The single-loop controller for process control is based on a high performance microcontroller in order to optimize the closed loop control of the system. The programming of the process control is carried out locally from the keyboard present on the control unit. The main function of the controller is to continuously control and monitor the process according to the programmed algorithm. The controller has the “auto-tuning” function. The programming of the characteristic parameters for P proportional, D derivative and I integrative is made by means of the pushbuttons present on the unit. A display provides the visualization of the variables during the
regulation (Set-point, process variable, etc).

TRAINING PROGRAM:
The equipment covers the following main subjects:
• Analysis of the structure of a digital process controller
• Programming of the controller functions
• Analysis of the regulation parameters: proportional, derivative and integrative coefficient
• Algorithms applied to the functional programming of a control
