1769-IF8 AB
About 1769-IF8
Allen Bradley’s 1769-IF8 compact I/O analog input module is an analog input module with eight (8) differential inputs, with voltage ranges of+/-10 VDC, 0 to 10 VDC, 0 to 5 VDC, and 1 to 5 VDC, and current ranges of 0 to 20 mA and 4 to 0 mA.
The back panel of 1769-IF8 draws a current of 120 mA at 5 V DC and 70 mA at 24 V DC, and emits 3.64 watts of heat during operation. It uses a Delta Sigma analog-to-digital converter with a resolution of 16 bit unipolarity or 15 bit plus sign. It has channel response speed that depends on the filter/configuration. It has a maximum bus draw current of 120 mA at 5 V DC, 70 mA at 24 V DC, an input impedance of 220 kilograms at the voltage end, and 250 ohms at the current end.
The 1769-IF8 has a common offset voltage range of+/- 10 VDC per channel and a common mode rejection ratio of more than 60 dB at 50 to 60 Hz. The total accuracy of the voltage signal of the analog input module is+/-0.2%, the total accuracy of the current signal is 0.35%, and the total drift accuracy of the voltage is+/-0.003%, and the current signal is+/-0.0045% per degree Celsius. It also has an input nonlinearity of+/-0.03% and repeatability of+/-0.03%. 1769-IF8 has an indicator light that displays the fault status of the module. 1769-IF8 performs automatic self diagnosis beyond or below the range through bit reporting, and it can also handle alarms. Its maximum input terminal overload is+/-30 volts DC, sustained at the 0.1 milliampere voltage terminal, and+/-32 milliampere overload at+/-7.6 volts DC. Its operating temperature range is between 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit), with a relative humidity limit of 95% and condensation. It weighs approximately 450 grams (0.99 pounds) and measures approximately 118 x 87 x 52.5 millimeters.
1769-IF8 is a Compact I/O module manufactured by Allen Bradley and compatible with 1769 CompactLogix controllers and MicroLogix 1500 controllers. This controller has embedded eight (8) input channels and supports differential and single ended wiring.
Configurable signals are 0-20 mA and 4-20mA, as well as+/10VDC, 1-5VDC, 0-5VDC, 0-10VDC.
