Allen Bradley 1746-NI16I Analog Input Module

The AB 1746-NI16I is a high-density analog input module designed for the SLC 500 platform. It features sixteen (16) individually isolated analog inputs, configurable to accept a range of current signals including 0…20 mA, 4…20 mA, ±20 mA, and 0…1 mA. The module enables precise and flexible current measurement across industrial applications and supports advanced diagnostics and scalable analog integration.

As a single-slot module, the 1746-NI16I integrates seamlessly into existing SLC 500 chassis without the need for additional configuration hardware, making it ideal for expansion or high-channel count signal acquisition.
