1769-IF4FXOF2F
The 1769-IF4FXOF2F is the combined I/O module of the 1769 Compact I/O product family. The module mainly has four (4) differential or single-ended analog input channels and two (2) single-ended analog output channels. Both analog input and analog output signals can be configured to ±10V, 0… 10V, 0… 5V, 1… 5V, 0… 20 mA and 4… 20.
The 1769-IF4FXOF2F analog input channel accepts ±10.5V -0.5V -0.5… 10.5V, -0.5… 5.25V, 0.5… 5.25V, 0… 21 mA and 3.2… 21 mah. It uses the successive approximation method to digitally convert the received analog signal, with a resolution of 14 bits for unipolar format conversion and 14 bits for symbolic or bipolar format conversion. The accuracy of the current signal in the input channel is ±0.2% full scale @ 25 °C (77 °F), the signal accuracy of the voltage signal is ±0.15% full scale @ 25 °C (77 °F), while the accuracy drift of the current is ±0.0045% per °C, and the accuracy drift of the voltage is ±0.003%.
The module’s analog output channel offers ± 10.5V-0.5V-0.5V… 10.5V, -0.5… 5.25V, 0.5… 5.25V, 0… 21 mA and 3.2… 21 mA., similar to input. It has a lower resolution because it offers either a unipolar 13-bit format or a 13-bit plus sign bipolar format. The module has a conversion rate of 1 ms, a step response of 63% of 2.0 ms, and an output accuracy of ±0.2% full scale @ 25 °C (77 °F).

It operates at 30 volts AC /30 volts DC with a range of ±10 volts DC per channel and a common suppression mode of >70 dB at 50 to 60 Hz.
The input impedance of the 1769-IF4FXOF2F voltage terminal is 220 kΩ and the input impedance of the input current terminal is 250 ohms. It has an overall input accuracy of 0.15% and 0.2% at voltage and current terminals. 1769-IF4FXOF2F has an overall accuracy drift of ±0.003% per degree Celsius at voltage terminals and ±0.0045% per degree Celsius at current terminals. It has ±0.03% input linearity and repeatability, with an error margin of 0.2% at 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit) voltage terminals and 0.3% at the same temperature range and input current terminals. Its maximum overload at the input voltage terminals is ±30 V DC (at 0.1 mA) and ±32 mA (at ±7.6 V DC). It has an isolation voltage of 30 volts AC /30 volts DC, tested IEC Class 2 enhanced insulation for 60 seconds at 500 volts AC between the input group and BUS isolation.
The 1769-IF4FXOF2F also features two single-ended outputs with a 13-bit monopole/bipolar converter resolution, conversion rates of 1.0 ms and 2 ms, and a response speed of 63%. The overall accuracy of the output is 0.2%, and the accuracy of the current and voltage terminals drifts to ±0.0086% and ±0.0058%. It also has an output isolation voltage of 30 volts AC and a 1-minute output group isolation test against IEC reinforced insulation at 500 volts AC. It weighs about 290 grams (0.64 pounds) and measures 118 x 87 x 35 mm (4.65 x 3.43 x 1.38 inches).
