1769-IF4FXOF2F

The Allen-Bradley 1769-IF4FXOF2F is a combination I/O module that is part of the 1769 Compact I/O product family. This module mainly features Four (4) Differential or Single-ended analog input channels and Two (2) Single ended analog output channels. Both analog input and analog output signals are configurable for ±10V, 0…10V, 0…5V, 1…5V, 0…20 mA, and 4…20. The analog input channels of the 1769-IF4FXOF2F accepts an analog signal voltage range of ±10.5V -0.5…10.5V, -0.5…5.25V, 0.5…5.25V, 0…21 mA, and 3.2…21 mA. It uses successive approximation method for digitally converting the received analog signal with conversion resolution of 14 bits in unipolar format and 14 bits with sign or bipolar format. The input channels has signal accuracy of ±0.2% full scale @ 25 °C (77 °F) for Current and ±0.15% full scale @ 25 °C (77 °F) for voltage signal while the accuracy drift with reference to temperature is ±0.0045% per °C for Current and ±0.003% per °C for voltage.

The analog output channels of this module can deliver analog signal range of ±10.5V -0.5…10.5V, -0.5…5.25V, 0.5…5.25V, 0…21 mA, and 3.2…21 mA., similar to the inputs. It has lower resolution as it provides 13 bits in unipolar format or 13 bits plus sign, bipolar format. The module’s conversion rate is 1 ms and step response to 63% of 2.0 ms while the output accuracy is ±0.2% full scale @ 25 °C (77 °F).

The module has selectable filter frequency of 5Hz, 10 Hz, 50 Hz, 60 Hz, 100 Hz, 250 Hz, 500 Hz and 1000 Hz.

It has 4 differential or single-ended analog inputs and is designed with an analog-to-digital successive approximation converter, with a filter-dependent channel response speed and a resolution of 14-bit unipolar/bi-polar. It has a functional voltage of 30 Volts AC/30 Volts DC with ±10 Volts DC per channel common offset voltage range, with a common rejection mode of >70 dB at 50 to 60 Hertz.

The 1769-IF4FXOF2F has an input impedance of 220 kiloΩ at the voltage terminal and 250 ohms at the input current terminal. It has an overall input accuracy of 0.15% and 0.2% at the voltage and current terminals The 1769-IF4FXOF2F also has an overall accuracy drift of ±0.003% per degree Celsius at the voltage terminal and ±0.0045% per degrees Celsius at the current terminal. It has ±0.03% input linearity and repeatability with a 0.2% error margin at 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit) at the voltage terminal and a 0.3% error at the same temperature range and at the input current terminal. It has a maximum overload of ±30 Volts DC at the input voltage terminal, at 0.1 mA, and ±32 mA at ±7.6 Volts DC, at the current terminal. It has an isolation voltage of 30 Volts AC/30 Volts DC, with IEC Class 2 reinforced insulation tested at 500 Volts AC for 60 seconds between an input group and BUS isolation.

The 1769-IF4FXOF2F also has 2 single-ended output with 13-bit unipolar/bipolar converter resolution and a conversion rate of 1.0 milliseconds and 2 milliseconds 63% response speed. Its output has an overall accuracy of 0.2%, with ±0.0086% and ±0.0058% accuracy drift at the current and voltage terminals. It also has an output isolation voltage of 30 Volts AC, with IEC Reinforce insulation tested at 500 Volts AC for 1 minute between output groups to BUS isolation. It weighs approximately 290 g (0.64 pounds) and has dimensions of 118 x 87 x 35 millimeters (4.65 x 3.43 x 1.38 inches).
