The ATR244 regulator sets new standards for the ATR range and further enhances its versatility. It stands out for its high performance display that guarantees excellent readability and increases the information that can be used by the operator in addition to a useful scrolling help function.

The programming mode with NFC / RFID technology is introduced through the App (already available in the range of converters and STR indicators), which allows programming in the field and on the move without the need for wiring or power supply.

Versions with single and double analogue input are available with the possibility to manage two processes and two separate control loops or to perform mathematical operations (sum, difference, average) between the two processes. The outputs can be selected as a command or multiple analogue alarm / retransmission modes.

The serial communication option is in RS485 with Modbus RTU / Slave protocol. Useful power supply with extended range from 24 to 230V AC / DC with galvanic isolation from the mains.
