Two-channel universal controller AR653

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)
• panel housing 96x48x79 mm, IP65 from the front, IP20 from the connectors
• power supply:
  • 230 Vac (85÷260 Vac) / 3 VA
  • 24 Vac/dc (18÷72 Vdc/ 3 W, 15÷50 Vac / 3VA)
• operating temperature range: 0÷50°C
• relative humidity range: 0÷90% (no condensation)
