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.)
2 universal measurement input(RTD, thermocouple TC, analog 0/4÷20mA, 0÷10V, 0÷60mV, 0÷2.5kΩ) with mathematical functions(diffrenence, sum, average, greater, or lesser of the measurements) available independenlty for displaying and controlling control/alarm output
2function 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 , keypad lock, reset of errors and alarms STB (LATCH), unconditional preview of measured values from inputs 1 and 2.
3control/alarm outputs of the on/off type (binary P/SSR) with independent functionalities and control algorithms(setpoints defined by the parameter or taken from the measurement input 1/2):
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 (choice of 3 separate sets of parameters, gain scheduling for SP setpoint taken from measurement input 1 or 2), 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/50mA
clear LED display with adjustable brightness and signaling of the operating status (messages, errors, etc.):
white color - measured value 1 (PV1, upper line), typical measurement units (°C, %, %RH, mA, A, mV, V, m and kPa, Pa, k for AR633.B/653.B or missing), symbols of outputs status and serial transmissions (1, 2, 3, . )
red, bottom line - selectable measured value 2 (PV2) or set SP or 8-segment bargraph for MV (control signal in the range of 0÷100%), PV (measurement), mA/V output signal or none
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)
freeARSOFT-CFGsoftware 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)
modern technical solutions, intuitive and simple handling, high accuracy and long-term stability as well as resistance to interferences
