Product Description

Available versions:

  • AR653.B - panel housing 96x48, IP65 from the front(with an accessory or other gasket), IP54 without a gasket
  • AR663.B - housing for DIN rail (35 mm), IP40 (IP20 connectors), dimensions 53x90x62 mm (without connectors)
  • AR633.B - industrial enclosure IP65 for operation in difficult environmental conditions, wall mounting, dimensions 120x80x55 mm (without cable glands)

Technical details:

  • control and supervision of temperature and other physical values (humidity, pressure, flow, level, velocity, etc.) converted into a standard electrical signal
  • configurable architecture enabling using in many fields and applications (industrial, heating, food, energy, etc.)
  • 2 universal measurement input(RTD, thermocouple TC, analog 0/4÷20mA, 0÷10V, 0÷60mV, 0÷2.5kΩ) with mathematical functions(diffrenence, sum, average, greater, or lesser of the measurements) available independenlty for displaying and controlling control/alarm output
  • 2 function keys (F and SET) and digital input (BIN) for quick change of the controller operating mode, separately programmable: control start/stop, manual/automatic mode for outputs, step change of the SP setpoint , keypad lock, reset of errors and alarms STB (LATCH), unconditional preview of measured values from inputs 1 and 2.
  • 3 control/alarm outputs of the on/off type (binary P/SSR) with independent functionalities and control algorithms(setpoints defined by the parameter or taken from the measurement input 1/2):
    • ON-OFF with hysteresis (threshold characteristics for heating and cooling, band alarms within and out of range and with an offset for three-state control)
    • PID (choice of 3 separate sets of parameters, gain scheduling for SP setpoint taken from measurement input 1 or 2), advanced functions of automatic selection of PID smart logic parameters
    • programmable operation characteristics (process controller with timer, up to 6 segments, including 3 segments of ramping type-slope for heating/cooling or cooling/defrosting, 3 SP setpoints with ON-OFF or PID control, selection of the auxiliary output and its condition, displaying the remaining time for the entire segment or after exceeding the SP, etc.)
    • thermostat/controller/safety switch STB (alarm condition open or closed, erased F/SET/BIN, can also be used as an alarm memory of LATCH type , e.g. after exceeding the minimum, maximum or band)
    • the ability to control a three-way mixing valve with an actuator (step control, servo) with two pin inputs (open - close), implemented on outputs 1 and 2
    • manual mode (open control loop) with the initial value of the control signal (MV) taken from the current automatic mode or programmed by the user in the range of 0÷100%, also for sensor failure
    • direct or reversed copy of the output 1 state (applies to outputs 2 and 3, it can be used, for example, to implement a DPDT change-over relay or to take over the function of a damaged P1)
    • limitation of the maximum level of the output signal (power), also includes the connected mA/V analog output
  • analogue output 0/4÷20mA or 0/2÷10V for adjustment or retransmission of measurements and setpoints:
    • download of the control parameters from any connected output/alarm (1, 2, 3), both in automatic and manual mode
    • shock-free (soft) switching of the output signal, e.g. after changing the manual/automatic mode or control start/stop
    • correction (calibration) of the range of changes of the output signal (shift for the extreme values allowing to obtain non-standard ranges, e.g. 2÷16mA or 1÷9V)
  • wide range of supply voltages (18÷265 Vac / 22÷350 Vdc) and built-in power supply for object transducers 24Vdc/50mA
  • clear LED display with adjustable brightness and signaling of the operating status (messages, errors, etc.):
    • white color - measured value 1 (PV1, upper line), typical measurement units (°C, %, %RH, mA, A, mV, V, m and kPa, Pa, k for AR633.B/653.B or missing), symbols of outputs status and serial transmissions (1, 2, 3, . )
    • red, bottom line - selectable measured value 2 (PV2) or set SP  or 8-segment bargraph for MV (control signal in the range of 0÷100%), PV (measurement), mA/V output signal or none
  • optional RS485 serial interface, MODBUS-RTU protocol for reading measurements and parameters configuration
  • optional Ethernet interface, MODBUS-TCP and MQTT protocols (for the Internet of Things IoT/M2M, cloud and mobile applications), the possibility to exchange measurement and configuration data via the Internet
  • USB interface (micro USB connector, standard equipment, for parameter programming, measurement preview and firmware update)
  • automatic/constant compensation of RTD and R line resistance and temperature of thermocouple cold junctions
  • programmable input type, range of indications (for analogue inputs), options of control, alarms, display, communication, access, and other configuration parameters
  • access to configuration parameters protected by a user's password or without protection
  • ways to configure parameters:
    • from the membrane keyboard placed on the front panel of the device
    • via the USB port, RS485 or Ethernet and the ARSOFT-CFG program (for Windows 7/10) or the user's application (using the MODBUS-RTU and TCP communication protocols)
  • free ARSOFT-CFG software enabling the preview of the measured value and quick configuration of single or ready sets of parameters previously saved on the computer for re-use, e.g. in other controllers of the same type (duplication of configuration)
  • modern technical solutions, intuitive and simple handling, high accuracy and long-term stability as well as resistance to interferences
