This 32x74 controller is highly configurable, which means it requires a lower number of product codes. The input can be programmed for  temperature sensors, resistance thermometers and thermocouples,   but also for pressure transmitters, humidity and flow sensors.

The algorithm for heating-cooling PID control is optimised both for temperature control and for process variables with quick transitory, like pressure control and flow control.

The software functions of the ATR121 include the open-close logic for valve control on industrial thermoregulation, air conditioning, dosing systems.

The controller's outputs can be selected as command/multiple alarm modes/event. The serial communication option is RS485 with Modbus/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 forum and via Skype.

The interface of the PID controller ATR121 ensures that the product is easy to use and that the user is also supported by auxiliaries for programming such as MEMORY-CARD or the 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.
