Allen-Bradley 1746-NI8 Analog Input Module

The Allen-Bradley 1746-NI8 is an eight-channel analog input module that accepts 4-20 mA current-loop signals from field sensors. Each of the eight inputs converts a 4-20 mA signal into a digital value that the PLC can read and use for monitoring and control. This configuration supports multiple process variables from sensors that output current loops, such as flow meters, pressure transducers, and level sensors, within a single module. The NI8 is part of the Allen-Bradley 1746 family, designed to provide expanded analog input capacity in industrial automation environments. By aggregating eight independent 4-20 mA inputs, it enables scalable signal collection for applications requiring parallel measurement channels without adding separate input modules for every sensor. It feeds real-time data into compatible controllers, supporting straightforward integration into existing automation architectures.
