Allen-Bradley 1746-NI16I 16-Channel Analog Input Module

The Allen-Bradley 1746-NI16I is a 16‑channel analog input module for the SLC 500 family that converts sixteen analog current signals into data the PLC can process on the I/O backplane. It is designed to read current-type inputs from field transmitters, enabling monitoring of process variables such as flow, pressure, and level through a single module in an industrial control panel. Commonly paired with RSLogix 500 programming workflows, the NI16I consolidates multiple analog current-loop signals into mapped data addresses for real‑time control and monitoring, simplifying wiring and panel layout. Typical applications include manufacturing process control, water and wastewater treatment, chemical processing, and batching systems where multiple current-loop signals must be sampled and routed into the PLC for automation tasks.
