1769 Compact I/O Modules Specifications
Table 18 - 1769-IF4FXOF2F Input Specifications
Attribute 1769-IF4FXOF2F
Inputs 4 differential or single-ended
Input range ±10V
0…10V
0…5V
1…5V
0…20 mA
4…20 mA
Full scale range
(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.
±10.5V
-0.5…10.5V
-0.5…5.25V
0.5…5.25V
0…21 mA
3.2…21 mA
Converter type Successive approximation
Resolution
(2)
(2) Resolution is dependent upon your filter selection. The maximum resolution is achieved with either the 50 or 60 Hz filter selected.
14 bits (unipolar)
14 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, both the plus and minus input terminals must be within ±10V DC of analog common.
±10V DC max per channel
Common mode rejection > 70 dB @ 50 and 60 Hz with the 10 Hz filter selected
Input impedance Current: 250 Ω
Voltage: 220 kΩ
Accuracy
(5)
(5) Includes offset, gain, nonlinearity, and repeatability error terms.
Current: ±0.2% full scale @ 25 °C (77 °F)
Voltage: ±0.15% full scale @ 25 °C (77 °F)
Accuracy drift with temperature Current: ±0.0045% per °C
Voltage: ±0.003% per °C
Nonlinearity ±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.
±0.03%
Module error Current: ±0.3%
Voltage: ±0.2%
Overload at input terminals, max
(7)
(7) Damage may occur to the input circuit if this value is exceeded.
