Allen-Bradley 1756-IF4FXOF2F Analog I O Module

Allen-Bradley 1756-IF4FXOF2F is a ControlLogix high-speed analog I/O module that combines four analog inputs and two analog outputs in a single 1756 backplane‑compatible module for fast mixed signal I/O. It accepts both voltage and current signals with selectable input ranges: voltage channels can be configured for -10 to +10 V, 0 to 10 V, or 0 to 5 V, and current channels for 0 to 20 mA with 4–20 mA operation, with an over-range indication when exceeded; the two output channels can drive -10 to +10 V or 4–20 mA. Backplane and supply requirements are 375 mA at 5.1 V for the backplane and 100 mA at 24 V, with a total power dissipation around 4.3 W; isolation is 250 V continuous between I/O and backplane, but there is no isolation between individual inputs or outputs. Data formatting options include integer mode (left-justified, 2's complement) and IEEE 32-bit floating point. Voltage inputs present >1 MΩ impedance, while current inputs present approximately 249 Ω. Operating temperature is 0 to 60 °C (32 to 140 °F). This module is suited for ControlLogix networks requiring simultaneous high-speed analog input and output in a compact 4/2 configuration for process monitoring, feedback control, and data acquisition in industrial automation.
