Allen‑Bradley 1756‑IF16 16‑Channel Analog Input Module

The Allen‑Bradley 1756‑IF16 is a 16‑channel analog input module designed for Rockwell ControlLogix PLC systems. It receives analog signals from field transmitters and converts analog process values into digital data, allowing the controller to monitor pressure, temperature, flow and liquid level variables for industrial closed‑loop control.

This hot‑swappable rack plug‑in module supports configurable current and voltage signal ranges with built‑in channel diagnostic functions. It fits standard ControlLogix chassis slots and is widely used in manufacturing, water treatment, petrochemical and power plant automation cabinets.
