Product Description

  • Ordering method and detailed technical information are in the catalogue card and manual, control, monitoring, and recording of temperature and other physical values (humidity, pressure, level, flow rate, speed, etc.) processed into a standard electric signal (0/4÷20 mA, 0÷10 V, 0÷60 mV, 0÷850 Ω), with the option of presenting 1 to 4 measurement channels,
  • 4 universal inputs (thermoresistance and analogue, no galvanic separation) with the option to create inter-channel mathematical formulas such as: difference, average, sum, larger, smaller from measured values;
  • 4 control/alarm outputs with independent control algorithms: ON-OFF with hysteresis, PID, PID autotuning, 12-step program adjustment
  • an optional module of 4 analogue outputs (0/4÷20 mA and 0/2V÷10V) and 5 functional binary inputs (BIN) to change the operating modes of the associated outputs (control start/stop, selection of the day/night set value, manual/automatic mode); the analogue outputs are logically connected to the two-state outputs (P/SSR) and are used for control or retransmission of measurements and set values; the inputs and the outputs have no galvanic separation (common ground);
  • selection of setpoints for outputs from: 2 defined for each output, the common value from the 1st output (without and with offset for 3-position control), from the selected program or any measurement input;
  • selection of independent PID sets (from the 8 available sets) for individual setpoints (gain scheduling);
  • advanced automatic PID parameter selection function with fuzzy logic elements for each of the outputs;
  • 4 programs with 12 section each with the possibility to define for each section such parameters as type (inclination/time/stop), set value, hysteresis, set of PID parameters, selection and status of auxiliary output, sound alarm, etc.;
  • time control/timer, options: continuous operation, periodic daily (hourly), or limited by date and time;
  • manual mode (open control loop) available for 2-state and analogue outputs with setting of the output signal value in the range of 0÷100% (the impulse period or the entire range of variability for mA/V analogue outputs);
  • shockless switching of analogue outputs from manual mode to automatic mode and vice versa;
  • possibility to select the measured values to be displayed and, independently, the type of control signals for the outputs (associated inputs or mathematic functions on the measurement signals, such as difference, average, etc.);
  • possibility to assign many outputs to one measurement channel and many inputs to one output;
  • available sound and visual signalling of the status of operation of outputs and email alarm notification;
  • recording of data in a standard text file located in the internal memory of the controller (4 GB) or an USB memory in a FAT system, with possibility to edit in spreadsheet software, e.g. Microsoft Excel
  • wide range of standard equipment with serial interfaces: USB (for working with PC and USB flash drives), RS485 (MODBUS-RTU) and Ethernet (100base-T, TCP/IP: MODBUS-TCP, HTTP, SMTP, etc.)
  • www server for work with any web browser (Opera, IE, Firefox, etc.); the site contains information about active measurement channels, setting status and parameters, status of the outputs, recording, etc., with the possibility to show diagrams using the Google Chart API service (constant Internet access is required), see more÷
  • DDNS service, which enables easy access over the Internet to a controller connected to a network that has no fixed public IP address, through a friendly Internet address defined by the user; the service is available only for registered users of popular DDNS services
  • colour LCD TFT graphic display 320x240 dots (QVGA), with a touch screen, brightness adjustment, and programmable background colour for individual measurement channels
  • intuitive use, quick configuration, and clear signalling of device operating statuses and menu position;
  • programmable language (Polish, English) for the menu, web server and other services
  • graphic and text methods of presenting the measured values (numerical values, bar graph, counter, graph);
  • grouping of measurement channels to be displayed, with automatic formatting of the screen (font size, etc.);
  • programmable screen function buttons (F1) for each of the displayed control channels for quick selection of one of the available functions (the same as for the binary inputs (BIN) of the optional module)
  • programmable "F" button for quick selection of one of the available functions: start/stop of recording or control for all outputs, status of device and internet services, copying archives to USB memory, locks, etc.
  • a broad selection of recording start methods (continuous, limited by date and time, periodic daily, above or below the permission threshold related to any measurement signal, only during control);
  • internal real time clock with a battery backup power supply (up to 8 years of continuous operation);
  • free software provided (for Windows 7/8/10) that enables presentation in a graphic or text form of the recorded results (ARsoft-LOG) and configuration of parameters (ARsoft-CFG)
  • programmable display options, presented measured values and control signals for the outputs (measurements, mathematic functions, etc.), types of measurement inputs, indication ranges, alphanumeric description of measurement channels and groups, control/alarm, recording, communication, and access options, and other configuration parameters;
  • passwords of the administrator and user for protecting operating parameters and modes against unauthorized modification.
  • methods for configuring parameters:
    • via membrane keyboard and a touch screen located on the front panel
    • via USB, RS485 or Ethernet and freeware ARsoft-CFG or user application, MODBUS-RTU and MODBUS-TCP communication protocols
    • from configuration files saved in the USB memory or on a computer disk;
  • recording of data until the memory is full (at least 2 years of continuous operation with recording of 4 channels every 1 s);
  • option of transferring archive and configuration data via USB port or Ethernet
  • simultaneous recording of data from all active measurement channels;
  • available protection of saved measurement data against unauthorized modification (check sum);
  • housing for panel installation, leak-tightness from the front IP65 or IP30 (depending on the version);
  • built-in 24 V DC power supply adapter for supplying on-site transducers (current output depending on the version);
  • line resistance compensation for resistive sensors and temperature of cold thermocouple ends (automatic or fixed)
  • high accuracy and immunity to interference
  • option of independent software update for the controller from USB memory;
  • power supply:
    • 230Vac network (85÷260 Vac) / 10VA
    • low-voltage (optional) 24Vac (20÷50 Vac) / 10VA, 24Vdc (22÷72 Vdc) / 10W
