Product Description

  • microprocessor controller for temperature and other physical quantities (humidity, pressure, level, speed, etc.) converted into a standard electrical signal
  • universal thermometer and analogue input:
    • 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
  • BIN digital input and programmable function button "F", for changing operational mode of the controller:
    • control start/stop
    • manual/automatic mode for outputs
    • two-position switching of the set value (day/night)
    • keyboard lock
  • 2 or 3 outputs of ON/OFF type (ON-OFF, control, 2- and 3-position) with the following characteristics:
    • output 1 (main): ON-OFF with hysteresis, PID, fuzzy logic (auto-tuning) PID
    • output 2, 3 (auxiliary/alarm): ON-OFF with hysteresis
  • analogue output 0/4÷20mA or optionally 0/2÷10V (constant-control, retransmission)
  • advanced function of selecting PID parameters with fuzzy logic elements
  • available for binary and analogue outputs, for setting the value of the output signal in the range of 0 ÷ 100%,
  • programmable operation characteristics (process controller, ramping)
  • built-in 24 Vdc power supply for supplying on-site transducers
  • two-line LED digital readout with adjustable brightness:
    • Upper display - measured value,
    • Bottom display - setpoint of output 1
  • RS485 serial interface, galvanically isolated, MODBUS-RTU (charged extra)
  • compensation of line resistance for resistance sensors
  • temperature compensation of thermocouple cold ends
  • programmable input, range of indications (for analogue inputs), options for adjustment, alarms, communication, access and other configuration parameters
  • access to configuration parameters is protected by the user's password
  • methods for configuring parameters:
    • via membrane keyboard (IP65) located on the front panel of the device;
    • via RS485 or AR955 programmer 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 controllers of the same type (duplicate configuration)
  • high accuracy, long-term stability and immunity to interference
  • measurement accuracy:
    • for RTD, mA, V, mV, Ω: 0.1% of the measurement range ±1 digit
    • for thermocouples: 0.2% of the measurement range ± 1 digit, additionally
  • response time: 0.25÷3 sec. (programmable)
  • power supply:
    • 230 Vac (85÷260 Vac) / 3 VA
    • 24 Vac/dc (20 ÷50 Vac / 3 VA, 20 ÷ 72 V dc / 3 W)
  • operating temperature range: 0÷50 °C
  • relative humidity range:  <100%RH
  • panel housing 120x80x55 mm
  • ingress protection rating: IP65
  • material: polycarbonate
