1769 Compact I/O Modules Specifications
Table 19 - 1769-IF4FXOF2F Output Specifications
Attribute 1769-IF4FXOF2F
Outputs 2 single-ended
Output 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
Resolution 13 bits (unipolar)
13 bits plus sign (bipolar)
Conversion rate (all channels), max 1 ms
Step response to 63%
(2)
(2) Step response is the period of time between when the D/A converter was instructed to go from minimum to full range until the device is at 63% of full range.
2.0 ms
Current load on voltage output, max 10 mA
Resistive load Current: 0…500 Ω (includes wire resistance)
Voltage: 1 kΩ or greater
Inductive load, max Current: 0.1 mH
Voltage: 1 μF
Field calibration None required
Accuracy
(3)
(3) Includes offset, gain, nonlinearity, and repeatability error terms.
±0.2% full scale @ 25 °C (77 °F)
Accuracy drift with temperature Current: ±0.0058% per °C
Voltage: ±0.0086% per °C
Output ripple
(4)
(4) Output ripple is the amount a fixed output varies with time, assuming a constant load and temperature.
±0.05% @ 0…50 kHz
Nonlinearity ±0.05%
Repeatability
(5)
(5) Repeatability is the ability of the input module to register the same reading in successive measurements for the same input signal.
±0.05%
Module error Current: ±0.4%
Voltage: ±0.3%
Open and short-circuit protection Yes
Short-circuit protection, max 50 mA
Output overvoltage protection Yes
Rated working voltage
(6)
(6) 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
Isolation voltage 500V AC or 710V DC for 1 min (qualification test), output group to bus
30V AC/30V DC working voltage (IEC Class 2 reinforced insulation)
