Description
The 1769-IF8 compact I/O analog input module by Allen-Bradley is an analog input module with Eight (8) differential inputs and a voltage range of +/-10 Volts DC, 0 to 10 Volts DC, 0 to 5 Volts DC, and 1 to 5 Volts DC, and current range of 0 to 20 mA, and 4 to 0 mA.
The 1769-IF8 has a backplane draw current of 120 mA at 5 Volts DC, and 70 mA at 24 Volts DC, and it dissipates 3.64 Watts of heat when it is operational. It uses the Delta -Sigma analog to digital converter, which resolution of 16-bit unipolar or 15-bit plus sign. It has filter/configuration-dependent channel response speed. It has a maximum Bus draw current of 120 mA at 5 Volts DC and 70 mA at 24 Volts DC, with an input impedance of 220 kilograms at the voltage terminal and 250 ohms at the current terminal. The 1769-IF8 has a common offset voltage range of +/-10 Volts DC per channel, and a common mode rejection ratio greater than 60 dB at 50 to 60 Hertz. This analog input module has an overall accuracy of +/-0.2% for voltage signals and 0.35% for current signal while the overall drift accuracy of +/-0.003% for voltage and +/-0.0045% per degree Celsius for current signal. It also has +/-0.03% input non-linearity and +/-0.03% repeatability. The 1769-IF8 has an indicator light which displays the module's FAULT status. The 1769-IF8 performs automatic self-diagnostics of over- or under-range by bit reporting and it can also process alarms. It has a maximum input terminal overload of +/-30 Volts DC continuous at the voltage terminal at 0.1 mA, and an overload of +/-32 mA at +/-7.6 Volts DC. Its operational temperature range is between 0 and 60 degrees Celsius (32 and 140 degrees Fahrenheit) at a 95% limit of relative humidity with condensation. It weighs approximately 450 grams (0.99 pounds) and it has approximate dimensions of 118 x 87 x 52.5 millimeters.
The 1769-IF8 is a Compact I/O module that is manufactured by Allen-Bradley in compatibility with 1769 CompactLogix Controller and MicroLogix 1500 controllers. This controller features an embedded Eight (8) Input channels that support differential and single-ended wiring. Configurable signals are 0-20 mA and 4-20mA and +/10VDC, 1-5VDC, 0-5VDC, 0-10VDC.
