Universal controller AR632

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
