  • Temperature drift 0.01 % F.S./℃
  • Response time reach 90 % of final value in 1 s
  • Insulation resistance ≥ 100 MΩ; 500 VDC (among power supply, input, output and the shell)
  • Electromagnetic compatibility according to IEC 61326-1 (GB/T 18268)
  • Weight approx 100 g
  • Field apparatus TC, mV Signal
  • Cold junction compensation accuracy: ± 1℃ (Compensation Bereich -20℃ ~ 60℃)

Power supply:

  • Supply voltage (Ue) 20 ~ 35 VDC
  • Power protection reverse protection of power supply
  • Current consumption ≤ 35 mA (at 24 Vdc supply, 20 mA output)
  • Power supply mode independent power supply
  • Power connecting mode terminal

Input data Signal:


Note:
- % of output accuracy is relative to the setting range, should take a bigger as relative error and absolute error as the output accuracy in application.
- TC input, transfer accuracy not contain cold junction compensation error. Every increase in compensation wire 100 Ω, cold end error increases 0.2°C.
- TC type B input, the lower limits of temperature range must be greater than 680°C, to meet the accuracy specifications.
- mV signal has to be customized.

Output data:
