Data recorder AR200.B

Product Description

• regulation, supervision and recording temperature and other physical quantities (humidity, pressure, flow, level, speed, etc.) converted into a standard electrical signal with the possibility of presenting from 1 to 3 channels with measurement data and their mathematical functions
• configurable architecture enabling using in many fields and applications (industrial, heating, food, energy, etc.)
• 2 universal measurement input (RTD thermo-resistive, TC thermocouple, analogue 0/4÷20mA, 0÷10V, 0÷60mV, 0÷2.5kΩ) with mathematical functions (subtraction, sum, average, larger or smaller of the measurements) available independently for displaying, recording and controlling control outpu
• recording data in the recorder memory in the FAT system, reading files via USB or Ethernet interface
• archive files saved in standard CSV text format with the option of reading and editing in available software or in any spreadsheets such as Excel or OpenOffice Calc, saving up to 3 channels (measurements and their mathematical formulas)
• 2 function buttons (F and SET) and digital input (BIN) for quick change of the recorder operation mode, programmable separately: start/stop of regulation and recording, manual/automatic mode for outputs, step change of the SP setpoint (day/night, i.e. SP1/SP3, with separate adjustment parameters), buttonpad lock, reset STB alarms (LATCH), quick change of SP setpoint, etc.
• 3 control/alarm channels (2 P/SSR hardware outputs + 1 software output) of on/off type with independent control functionalities and algorithms (SP setpoints defined by parameter or taken from inputs 1/2 measurements):
  • ON-OFF with hysteresis (threshold characteristics for heating and cooling, band alarms within and out of range and with an offset for three-point control)
  • PID (3 separate sets of parameters to choose from), 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 for slow-changing processes (e.g. for central heating CO, not recommended e.g. for CWU installations requiring a quick response to changes)
    
  • 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
  • acoustic and visual signaling of the operating status of the outputs (low-volume buzzer and displayed icons)
• analogue output 0/4÷20mA or 0/2÷10V for regulation 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)
  • the possibility of using an SSR relay for control (as a 3rd ON-OFF control output
• time control/timer, options: continuous operation, periodic daily (hourly), or limited by date and time
• wide range of supply voltages (18÷265 Vac / 22÷350 Vdc) and built-in power supply for object transducers 24Vdc/30mA
• OLED graphic display, 128x64 dots, single-color, with brightness adjustment and status indication, presentation of up to 3 measurement channels in various view modes (text, graph, bar graph, etc.)
• RS485 serial interface, MODBUS-RTU protocol for reading measurements and parameters configuration
• 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 reading recorded data, programming parameters, viewing measurements, access to internal memory and for updating firmware)
• automatic/constant compensation of RTD and R line resistance and temperature of thermocouple cold junctions
• programmable input type, indication range (for analog inputs), options for recording, adjustment, alarms, display, communication, access, real-time clock, menu language (Polish and English) and other configuration parameters
• programmable password protection against unauthorized access to archive and configuration data and a checksum to detect archive modifications
• 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 protocols)
• free software (for Windows 7/10/11) enabling reading and graphic or text presentation of recorded results (ARsoft-LOG) and preview of current measurements, as well as configuration and copying device parameters (ARsoft-CFG), available updates on the website
• a wide selection of ways to start recording (continuous, Limited by date and time, cyclic daily, only during adjustment/alarm or manually controlled with F, SET buttons or digital input BIN)
• distinguishing archives from multiple recorders by assigning an identification number (ID)
• record in infinite mode (after filling the memory, the oldest archives are deleted) or till the memory is full (recording is stopped), total capacity up to about 94 thousand records (when recording one measurement channel, minimum 80 thousand for 2, 71 thousand for 3)
• internal clock with the possibility of precise correction of real time counting
• panel housing, protection class IP65 from the front (after using an additional accessory gasket or other seal), IP54 without a gasket
• modern technical solutions, intuitive and simple handling, high accuracy and long-term stability as well as resistance to interferences
• optional (in the ordering procedure): control outputs for SSR and analog output 0/2÷10V (instead of standard one 0/4÷20mA)
