Four Loops PID Digital Controller

As with the present generation of PID controllers, the Four Loops PID Digital Controller has a structure based on a high performance microcontroller, analog inputs and outputs, programming of the regulation functions and serial interface for the communication with Personal Computers.

The programming of the main parameters of the process control is carried out locally through the touch screen display.

The controller can find immediate application to the control of various processes (temperature, pressure, flow rate and level) since it is designed to interface with those modules.

It is provided with an Ethernet interface in order to be connected to a Personal Computer for data visualization and control.

The main function of the regulator is to control and monitor the process continuously according to the programmed regulation algorithm. The regulator controls 4 auto-tuning regulation loops.

The parameters for the P- proportional, D- derivative and Iintegrative regulation are set via the touch screen display or via the PC.

The high resolution display shows the numerical or graphic trend of the variables during the regulation (Set point, Regulated quantity, Error…).

Training Program:

The equipment allows a wide range of educational applications such as:

  • Analyzing the structure of a digital process regulator
  • Programming the functions of the regulator;
  • Analyzing the parameters: proportional, derivative and integrative coefficient;
  • Analyzing the analog I/O signals and the connections with the process regulation;
  • Applying algorithms to the functional programming of a digital process control;

1 Ethernet interface for parameterization / supervision via PC of the regulator with Modbus TCP/IP protocol.
