PRODUCT INFORMATION
Product Overview
Revision scope: These specifications describe 1746-NI8/A (Series A). Check the corresponding technical data before specifying another hardware series.
The Allen-Bradley 1746-NI8 is a high-resolution analog input module for the SLC 500 control platform. This module mounts into any open slot of a standard SLC 500 chassis. It interfaces directly with field sensors through eight configurable analog input channels. The hardware converts analog field signals into digital data using 16-bit conversion resolution. It draws 75 mA of current at 5 V DC directly from the chassis backplane.
The 1746-NI8 module supports voltage ranges of ±10 V, 0-10 V, 0-5 V, and 1-5 V. Current input ranges support standard 0-20 mA and 4-20 mA instrument current loops. Channel-to-backplane electrical isolation is rated at 500 V AC for circuit protection. Hardware revisions include Series A units deployed across industrial SLC 500 systems.
