PID controller ATR444 integrates all functionalities of the Pixsys Blu Line controllers.

The bright alphanumeric display allows optimal visibility in all industrial environments, not only for process and alarm variables but also for scrolling status/event text messages, as well as for online help messages.

Keypad now includes 8 keys with the possibility to program single keys for dedicated functions, allowing direct access from front panel to frequent operations or functions which could result complex or time-spending for the user.

Programming mode by smartphone with MyPixsys Apprelies on NFC technology, not requiring any wirings, power supply or special hardware, making it also a useful remote assistance tool for the possibility to share configuration files via common messaging applications.

Two universal analogue inputs allowing mathematical operations (differential, average, sum) , extensive combination of analogue and digital outputs, open/close logics for valves, multiple alarm and diagnostic functions, timer mode: the most complete models of ATR444 support advanced applications which traditionally may require programmable logics.

Up to two PID control loops can be handled in heating/cooling mode, with a flexible algorithm which is optimised also for fast processes or those requiring high accuracy.

Some versions also integrate the programmer mode for the management of a cycle / profile with 12 segments.

Connectivity includes RS485 and ModbusRTU protocol, with the possibility of using the controller also with Pixsys CNV580 IIoT gateway for remote monitoring of selected variables and activation of notifications via PixsysGuard App.
