Scaling Resolution: The scaling stage depends on the range
selected.
Output Resolution: The output stage resolves to 1 part in 6546 for a 4
to 20mA output span. Note that input temp resolution is limited to 0.1
°
C
(TC inputs). Thus, the effective resolution is controlled by the output
stage for TC input spans greater than 655
° C (resolves 1 part in 6546),
or the input stage for TC input spans less than 655
°
(resolves to 0.1
°
C).
For the millivolt input range, the effective resolution is controlled by the
output stage (resolves to 1 part in 6546).
Current Output Specifications:
Output: 4-20mA DC
Output Range: 4 to 20mA DC, 3.8 to 25mA range typical.
Output Ripple: Less than ± 0.01% of output span.
Output Limiting: Output current is limited to less than
25mA, typical.
Output Compliance: 17V Minimum, 18V Typical, with a 24V
supply and 20mA loop current.
