The Allen-Bradley 1756-IF8 is a ControlLogix eight-channel, non-isolated analog input module for reading voltage and current signals on the 1756 backplane. Each of its eight channels can be configured for voltage or current input, with supported ranges including 0-10.25 V, +/-10.25 V, 0-5.125 V, and 0-20 mA. The module uses a 36-pin connector and installs in a 1756 backplane, drawing power from the chassis' backplane rails (5.1 V up to 150 mA and 24 V up to 40 mA). It is intended for use in industrial automation to acquire sensor data for ControlLogix-based systems.
