The AR503 is a mini panel meter of the standard DIN 72x24mm format accepting Volts, mV, 4-20mA, thermocouples, RTD sensors and resistances. Also supplied with a RS485 port for Modbus RTU communications and an analogue output for measureed value re-transmission. Configured using free software.

Special Offer:  Discounts of 7%, 10%, 12.5% and 15% are available when you order 10, 25, 50 and 100 items or more of this product.

  • digital meter of temperature and other physical quantities (humidity, pressure, level, speed, etc.) converted into a standard electrical signal (0/4÷20mA, 0÷10V, 0÷60mV, 0÷2.5 kΩ)
  • universal thermometric and analogue measuring input with the memory for storing minimum and maximum measured values:
    • thermoresistance Pt100, Ni100, Pt500, Pt1000
    • thermocouple J, K, S, R, T, B, E, N
    • current 0-20 mA, 4-20 mA
    • voltage 0-10 V, 0-60 mV
    • resistance 0-2500 Ω
  • remote data display via RS485 (MODBUS-RTU, SLAVE)
  • BIN programmable digital input for changing operational mode of the meter:
    • manual / automatic mode for analogue output
    • keyboard lock
    • Display HOLD function
  • analogue output 0/4÷20mA or 0/2÷10V (retransmission, alarm/control, manual)
  • Manual mode for the analogue output (open control loop), for setting the output value within 0 ÷ 100%
  • built-in 24Vdc power supply for supplying on-site transducers
  • RS485 serial interface, galvanically isolated, MODBUS-RTU
  • compensation of line resistance for resistance sensors
  • temperature compensation of thermocouple cold ends
  • programmable input, range of indications (for analogue inputs), options for alarm, display, access and other configuration parameters
  • access to configuration parameters is protected by the user's password
  • methods for configuring parameters:
    • programming via keypad accessible by removing the front shield
    • via RS485 or PRG port (programmer AR955/GP) and freeware: ARsoft-LOG (Windows 7/8/10)
  • 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 meters of the same type (duplicate configuration)
  • panel housing, IP54 from the front
  • high accuracy, long-term stability and immunity to interference



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
