1.3 - Technical Specifications
Inputs:
Two thermocouple configurable inputs (J, K, T, E, R, S, under ITS - 90), RTD Pt
- 100 under DIN 43760, 4 to 20mA, 0 to 55mVdc, 1 to 5Vdc, 0 to 10Vdc. Input
impedance of 250 Ω for mA, 10M Ω for 5Vdc and 2M Ω above 5Vdc. Table 1 shows
the temperature range limits for thermocouple and RTD and the resolution for the
linear input sensors.
