The Allen-Bradley 1746-NI16I is a high-density analog current input module designed for the SLC 500 programmable logic controller platform. It provides 16 single-ended input channels, making it an excellent solution for applications requiring the monitoring of multiple analog signals such as pressure, temperature, or flow transmitters. This module offers high-resolution data acquisition, converting analog current signals into digital values that the SLC 500 processor can use for precise process control and monitoring. Its user-configurable input ranges and scaling capabilities provide flexibility for a wide variety of industrial automation tasks.
