• 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.
