Two-channel universal controller AR663

Two-channel controller of temperature and standard signals, mathematical functions, 3 relay outputs/SSR, analogue output, ON-OFF, PID (autotuning, fuzzy logic), RAMPING, RS485, for DIN rail

Product Description

  • two-channel, microprocessor controller for temperature and other physical quantities (humidity, pressure, level, speed, etc.) converted into a standard electrical signal
  • mathematical functions - difference, sum, average of measurements
  • 2 universal inputs:
    • thermoresistance Pt100, Pt500, Pt1000, Ni100
    • thermocouple J, K, S, B, R, T, E, N
    • analogue 0/4÷20 mA, 0÷10 V, 0÷60mV
    • resistance 0 ÷ 2500 Ω
  • programmable function button for changing the operational mode of the controller: control start/stop mode, manual/automatic mode for outputs, two-position switching of the set value (day/night), keypad lock, preview of measured values
  • 3 independent outputs of ON/OFF type (ON-OFF, control, 2- and 3-position) with the following characteristics:
    • output 1 (main): ON-OFF with hysteresis, PID, PID AUTO-TUNING
    • output 2, 3 (auxiliary/alarm): ON-OFF with hysteresis
  • analogue output 0/4÷20 mA (constant-control, retransmission)
  • selecting control value outputs (measuring input, difference, sum, average from measurements)
  • advanced function of selecting PID parameters with fuzzy logic elements
  • manual mode for output control (in the range of 0÷100% of the output signal)
  • ramping of the process curve with timer
  • built-in 24 Vdc power supply for supplying on-site transducers
  • two-line LED display with adjustable brightness:
    • Upper display - measured value 1 (input 1, difference between measurements, etc.).
    • Bottom display - measured value 2 or setpoint
  • programmable display values (measurements or mathematical functions), input types, indication ranges (for analogue inputs), options for adjustment, alarms, communication, access and other configuration parameters
  • password-protected access to configuration parameters
  • option of blocking changes to the set values
  • programming via the keypad or AR955 programmer enabling also fast copying of all configuration parameters
  • ARsoft-CFG freeware for configuration of parameters
  • high accuracy and resistance to interference occurring in industrial environments
  • optional:
    • RS485 interface, MODBUS-RTU, galvanic separation
    • output 0/2÷10 V constant-control, retransmission (instead of 0/4÷20 mA)
  • 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: 0÷90 %RH (no condensation)
  • housing for rail mounting on TS35 rail (DIN EN 50022-35)
  • ingress protection rating: IP20
  • material: ABS/PC
