Process controller ATR144 is latest release of Pixsys controllers size 32x74mm, integrating recent Blue line standards that have been introduced with ATR244.  It stands out for bright display, ensuring optimal visibility in industrial environments and making available more information for the operator as well as a scrolling Help function.

ATR144 is programmable by NFC with dedicated App MyPixsys for Android devices (same already in use for Pixsys latest product lines), not requiring wirings and power supply and allowing quick set-up/updates on site.

Multi-voltage power supply 24 to 230V AC/DC with galvanic isolation does not require any hardware selection. Optional serial communication via RS485 with Modbus RTU/Slave protocol.


User friendly, multimedia support and traceability 

For the entire range of Pixsys products we provide technical support for installation, programming and operation via our online forumand via Skype.

The interface of the controller ATR144 is user-friendly; operator is also supported by programming tools such as  MyPixsys App (for Android devices) and LABSOFTVIEW programming software.

Programming tutorial videos are available on our YouTube channel. As for the entire range of PIXSYS products, thanks to the QR code the traceability of the product is guaranteed for its entire life cycle; the information and documentation online can be also be accessed by reading the QR CODE that directs your mobile device to the product's technical specifications and verifies its warranty conditions.
