ITI 17 is a programmable digital panel meter 96 x 48 mm for process and temperature by resistive probes and thermocouple measurements. The software enables additional linearization to be set up for thermocouples type B, C, E, L, Mo, N, PI, R, U and Pt100, Pt25 and Pt50. The connection of the probes is done using a removable screw connector.

  • Panel meter size: 96 mm x 48 mm
  • IP65 protected
  • Two-color display for color change on alarm or pre-alarm
  • Process signal measurement (0/4-20 mA, 0/100 mV /1 V / 10 V)
  • Temperature measurement by Pt100 from -200°C to +850°C (0.01°C resolution up to 200°C) or by thermocouple type K, T, J or S
  • Resistance measurement (10 mOhms to 400 Ohms)
  • 2 different power supplies available:
    • 90 to 260 V~ 47/420 Hz and 115 to 300 V-
    • 20 to 60 V- and 18 to 44 V~ 47/420 Hz

3 versions:

  • Version 0 : Panel meter only
  • Version 1 : 2 limit relays, 1 programmable analogue output (4-20 mA or 0-10 V), 1 digital output RS232/485, MODBUS/ASCII
  • Version 2 : 2 limit relays
