The Allen-Bradley 1746-NI16V is a high-density analog voltage input module designed for the SLC 500 programmable controller platform. It features 16 single-ended, non-isolated input channels, making it an efficient solution for applications requiring multiple analog voltage measurements. This module is capable of reading signals within a -10V to +10V DC range, converting them into high-resolution 16-bit digital values for processing by the SLC 500 CPU. It is ideal for monitoring and controlling processes involving sensors that output analog voltage, such as pressure transducers, flow meters, and potentiometers, providing precise data for industrial automation systems.
