Input Specifications
Attribute
Value
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.
±10V DC, 0 …10V DC, 0…5V DC, 1…5V DC
Full scale analog ranges
(1)
±10.5V DC, -0.5…10.5V DC, -0.5…5.25V DC, 0.5…5.25V DC
Number of inputs
16 single-ended
Converter type
Sigma Delta
Response speed per channel
Input filter and configuration dependent.
(8)
(8) Refer to the Compact High-Density Analog Input Modules User Manual, publication
Resolution, max
(2)
(2) Resolution is dependent upon your filter selection.
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 voltage range
(4)
(4) For proper operation, the plus input terminals must be within ±10V DC of analog common.
±10V DC maximum per channel
Common mode rejection
greater than 60 dB at 50 and 60 Hz with the 16 Hz filter selected,
respectively.
Input impedance
Greater than 1 M
Ω
(typical)
Overall accuracy
(5)
(5) Includes offset, gain, non-linearity and repeatability error terms.
0.35% full scale at 25 °C (77°F) for 16 Hz, 50 Hz, and 60 Hz filters
Accuracy drift with temperature
±0.003% per °C
Calibration
None required
Non-linearity (in percent full scale)
±0.03%
Repeatability
(6)
(6) Repeatability is the ability of the input module to register the same reading in successive measurements for the same input
signal.
±0.06% for 16 Hz filter
Module error over full temperature
range
(0…60 °C [32 °F…140 °F])
1.0% for 16 Hz, 50 Hz, and 60 Hz filters
Channel diagnostics
Over- or under-range by bit reporting, process alarms
Maximum overload at input terminals
(7)
(7) Damage may occur to the input circuit if this value is exceeded.
±30V DC continuous, 0.03 mA
Input group to bus isolation
500V AC or 710V DC for 1 minute (qualification test)
30V AC/30V DC working voltage (IEC Class 2 reinforced insulation)
