  • control of temperature and other physical parameters (humidity, pressure, level, speed, etc.) processed into a standard electric signal (0/4-20mA, 0-10V, 0-60mV, 0-2,5kΩ)
  • 2 universal measuring inputs (thermoresistance, thermocouple and analogue) with additional features:
    • mathematical (difference, sum and average of measurements from two inputs)
    • with measured minimum and maximum value saved in the memory
    • remote data display (via MODBUS-RTU, slave)
  • real-time clock displayed alternately with measurements
  • LED display: 4 digits, height 57 mm, 4 colours (red, orange, yellow, green)
  • programmable display colours for measurement channels, clock, LED indicators and alarms
  • 2 independent on/off alarm outputs (ON-OFF, heating, cooling, relative alarms, manual mode) with LED indication and a colour display
  • BIN digital input for switching the operating mode: start/stop for outputs, manual/automatic mode for outputs, two-position switching of the set value (day/night) for alarms, display "Hold" feature for measurements, changing or stopping the switching of displayed channels, direct display of measured value inputs (for mathematical functions), etc.
  • analogue output 0/4-20mA or 0/2-10V (alarm, retransmission)
  • option of converting an input signal into a standard analogue output
  • selecting control value outputs (input, difference, sum, average from measurements)
  • manual mode (open control loop) available for binary and analogue outputs, setting the value of the output signal in the range of 0 ÷ 100%, option of auto-activation due to sensor failure
  • built-in 24Vdc/50mA power supply adapter for supplying on-site transducers
  • RS485 serial interface, galvanically isolated, MODBUS-RTU, slave
  • compensation of line resistance for resistance sensors
  • temperature compensation of thermocouple cold ends
  • programmable display values (measurements, mathematical or remote functions), input types, indication ranges (for analogue inputs), alarm options, communication, access, display and other parameters
  • option of protecting access to the configuration of parameters with user password
  • methods for configuring parameters:
    • via membrane keyboard (IP65), located on the front panel of the device       
    • via RS485 or PRG (programmer AR956/955) and freeware ARsoft-LOG (Windows 7/8/10), MODBUS-RTU
  • software and programmer allow you to view the measured value and quickly configure single or few sets of parameters previously saved in the computer for re-use, e.g. in other devices of the same type (duplicate configuration)
  • high accuracy, long-term stability and immunity to interference
  • optionally (when ordered): 24V ac/dc power supply adapter, SSR alarm outputs, analogue output 0/2÷10V
  • power supply: 230Vac (85-260 Vac) /5VA, 24Vac/dc(18-72Vdc/5W,15-50Vac/5VA)
  • operating temperature range: 0-50 °C
  • wall-mounted housing 300 x 106 x 55 mm, made of aluminium profile, IP51



ARsoft-CFG application allows you to configure and readout current measurements carried out by AR series devices (controllers, meters, transducers, recorders, etc.) equipped with communication interface RS232, RS485, USB or Ethernet.

The application has the following features:

  • visualization of all available measurements for the selected type of device
  • fast, on-line editing of device parameters
  • window for configuring parameters includes textual descriptions of parameters and their range of variation
  • reading and recording device configuration with an option of text edition of the created file.

Hardware requirements:

  • Operating System: Windows 7/8/10
  • depending on the type of communication interface of the device connected:- COM port RS232 or RS485 (it is also possible to use converter from USB to RS232/RS485)- USB port- Ethernet network card
