Page 5: Presentation
PRESENTATION N1020 is an extremely versatile process controller. In a single model, it accepts most sensors and signals used in industry and provides the main types of output needed to act on several processes. Configuration can be carried out directly on the controller or, once the QuickTune software has been installed on the computer to be used, via the USB interface. -
