Overview

The Allen-Bradley 1746-NI16I is a high-density 16-channel analog current input module designed for the SLC 500 programmable controller platform. The module provides precise acquisition of analog current signals from field instruments and process devices, enabling accurate monitoring and control of industrial processes.

The 1746-NI16I accepts multiple current input signals from transmitters, sensors, and measurement instruments, converting them into digital data for processing by the PLC. Its high channel density makes it ideal for applications requiring centralized monitoring of numerous process variables while minimizing rack space requirements.

Widely deployed in process industries, manufacturing facilities, power generation plants, water treatment systems, and oil & gas installations, the module delivers reliable analog signal acquisition and long-term operational stability.
