The ATC990 Process Controller provides a cost-effective way to control a single process parameter, such as for a plastics extruder. Designed to improve user efficiency many features are integrated to reduce commissioning time, simplify operation and minimize maintenance downtime. Reliably auto-tune and alarm on strain gauge, DC voltage, temperature or current inputs. The ATC990 can also control differential pressure when an optional secondary strain gauge input is used.

■ Auto-tuning control in a discrete 1/4 DN package

■ Graphical/text LCD Display with color change LED backlight on alarm (red/green)

■ Graphical trend view of process alarms & events as standard

■ Easy to use Setup Wizard

■ Single loop control

■ USB port option logs process values, set points and alarms to .csv file for use with spreadsheets

■ Modbus RS-485 and Modbus TCP Ethernet supported

■ BlueControl configuration and commissioning software option
