ATC990 Process Controller
The ATC 990 with graphic / text LCD display is a universal input controller with advanced functions including trend display, digital inputs, data logging and USB port. It provides a cost-effective way to control process parameters, for example for extrusion applications. Designed to increase efficiency and user comfort, it includes features that reduce commissioning time, simplify operation and minimize maintenance downtime. Automatic tuning, setting of external power supply alarms, various inputs (temperature / pressure).
The ATC 990 can also operate and control the process based on differential pressure if the optional mv / v input is used. Other useful information displayed directly on the top of the controller by means of LEDs is alarms, upper or lower limits, error states and beacons of engineering units. The control unit provides quick and easy setup, which includes a step-by-step setup wizard that starts automatically the first time it is started.
An optional 24 V DC power supply is also available.
