PRODUCT INFORMATION
Product Overview
Revision scope: These specifications describe 1746-NI4/A (Series A). Check the corresponding technical data before specifying another hardware series.
The Allen-Bradley 1746-NI4 is an SLC 500 analog input module designed for process signal acquisition. It provides four high-resolution analog input channels for industrial automation chassis. The module accepts selectable differential or single-ended wiring configurations. Backplane current draw requires approximately 55 mA at 5 V DC. The operating temperature ranges from 0 to 60 degrees Celsius.
This module delivers 16-bit conversion resolution for incoming instrumentation loops. Compatible signal inputs include current ranges of 4 to 20 mA and 0 to 20 mA. It converts bipolar voltage signals including plus or minus 10 V DC. Unipolar voltage ranges include 0 to 10 V, 0 to 5 V, and 1 to 5 V DC. This conversion capability enables precise measurement for industrial control systems.
