Product Description

  • 1 universal measurement input:
    • thermoresistance Pt100, Ni100 (2- and 3-wire with line resistance compensation)
    • thermocouple: J, K, S, B, R, T, E, N, compensation of temperature of cold ends
    • analogue: current 0/4÷20mA, voltage 0÷10V, 0÷60mV, resistance 0÷1000Ω
  • 1 alarm/control output with signalling operational status
  • USB and RS485 serial interface (galvanically isolated, MODBUS-RTU) to configure the device and read the current measurements
  • saving data in a standard text file stored in the recorder's internal memory, SD or USB stick in FAT system
  • option of transferring archive and configuration data on SD card, USB memory or using the USB port of a computer
  • 7-segment LED display with adjustable brightness
  • internal real time clock with a battery backup power supply
  • built-in 24Vdc power supply for supplying on-site transducers
  • compensation of line resistance for resistance sensors
  • temperature compensation of thermocouple cold ends (automatic or fixed)
  • free software provided for displaying recorded results as graphics or text and for configuring the parameters
  • programmable input, range of indications, options for recording, alarm, communication, access and other configuration parameters
  • methods for configuring parameters:
    • via membrane keyboard (IP65) located on the front panel of the device;
    • via USB or RS485 interface and a computer program (Windows 7/8/10)
    • from the configuration files saved on SD or USB memory
  • access to configuration parameters is protected by the user's password
  • available data protection against unauthorized copying and modification (checksum, authorization request for SD card and USB memory)
  • possibility to differentiate archives from many recorders of the same or similar type by assigning individual identification numbers (ID);
  • signalling the presence of SD memory and USB, and file operations
  • saving data until the memory is full
  • option of updating firmware of the recorder
  • high accuracy and immunity to interference
  • panel housing 96x48mm, IP65 from the front
