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.)
  • 1 universal measurement input (RTD, thermocouple TC, analog 0/4÷20mA, 0÷10V, 0÷60mV, 0÷2.5kΩ)
  • 2 (1 for AR602.B) 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 (day/night, i.e. SEt1 / SEt3 , with separate control parameters), keypad lock, reset of errors and alarms STB (LATCH), etc.
  • 3 (2 + 1 LED alarm for AR602.B) control/alarm outputs of the on/off type (bi-state P/SSR) with independent functionalities and control algorithms:
    • 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 (3 separate sets of parameters to choose from), 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/30mA
  • clear LED display with adjustable brightness and signaling of the operating status (messages, errors, etc.):
    • white color - measured value PV (upper line), typical measurement units (°C, %, %RH, mA, A, mV, V, m and kPa, Pa, k for AR632.B/652.B/682.B or missing), symbols of outputs status and serial transmissions (1, 2, 3, . )
    • red, bottom line - selectable SP setpoints or 8-segment bargraph for MV (control signal in the range of 0÷100%), PV (measurement), mA/V output signal or missing
  • 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)
  • panel housing, protection class IP65 from the front (after using an additional accessory gasket or other seal), IP54 without a gasket, AR662.B - housing for mounting on the TS35 rail (DIN EN 60715), IP40 (IP20 from the connectors side),B - industrial housing IP65 adapted to work in difficult environmental conditions, wall mounting

  • optional (in the ordering method): control outputs for SSR, analog output 0/2÷10V (instead of 0/4÷20mA) and RS485 interface (for AR602.B excludes mA/V output and BIN input) and Ethernet (RJ45 connector)
  • available accessories (you can also buy it through the online store apar.sklep.pl):
