Analog Normal Operating
Ranges
(1)
(1) The over- or under-range flag will come on when the normal operating range (over/under) is exceeded. The
module will continue to convert the analog input up to the maximum full scale range. The flag automatically
resets when within the normal operating range.
Voltage: ± 10V dc, 0…10V dc, 0…5V dc, 1…5V dc
Current: 0…20 mA, 4…20 mA
Full Scale Analog
Ranges
(1)
Voltage: ± 10.5V dc, 0…10.5V dc, 0…5.25V dc, 0.5…5.25V dc
Current: 0…21 mA, 3.2…21 mA
Number of Inputs 4 isolated differential
Bus Current Draw, Max 145 mA at 5V dc
125 mA at 24V dc
Heat Dissipation 3.0 total W (The W per point, plus the min W, with all points
energized.)
Converter Type Delta Sigma
Response Speed per
Channel
Input filter and configuration dependent. See Filter Frequency
and Update Times on page 3-9.
Resolution, Max
(2)
(2) Resolution is dependent upon your filter selection. The maximum resolution is achieved with the 10 Hz filter
selected.
16 bits (unipolar)
15 bits plus sign (bipolar)
Rated Working Voltage (3)
(3) Rated working voltage is the maximum continuous voltage that can be applied at the input terminal, including
the input signal and the value that floats above ground potential (for example, 10V dc input signal and 20V dc
potential above ground).
30V ac/30V dc
Common Mode Rejection Greater than 60 dB at 50 and 60 Hz with the 10 Hz filter
selected, respectively.
Normal Mode Rejection
Ratio
-50 dB at 50 and 60 Hz with the 10 Hz filter selected,
respectively.
Input Impedance Voltage Terminal: 1 Mtypical)
Current Terminal: 249 
Overall Accuracy (4)
(4) Includes offset, gain, non-linearity and repeatability error terms.
Voltage Terminal: ±0.2% full scale at 25 °C
Current Terminal: ±0.35% full scale at 25 °C
