ES650.1 - User Guide
14
The channels for analog input voltages have two input voltage ranges. The res
-
olution is 16 bits, the inaccuracy is 2 mV in the 10 V range or 12 mV in the 60 V
range, depending on the input voltage.
The thermocouple channels have a resolution of 21 bits. You can use B-, E-, J-,
K-, N-, R-, S- and T-type thermocouples. The maximum measuring range is
-
210 °C to +1,820 °C. Each thermocouple channel is fitted with a cold junction
compensation directly in the connector. This ensures accuracy even when the
housing is not heated uniformly. The thermocouples are galvanically isolated
from each other and from case ground.
