- Configure every 1746-NI8 channel for the documented voltage or current source
- Keep field commons, shields and external transmitter power within the approved design
- Preserve switch settings, software ranges, scaling and filter values before replacement
Allen-Bradley 1746-NI8 is an eight-channel SLC 500 analog input module with independently selectable voltage or current operation on each channel.
Allen-Bradley 1746-NI8 is an eight-channel SLC 500 analog input module with independently selectable voltage or current operation for each channel. 1746-NI8 is the complete catalog number. Official conformity documentation identifies Series 1 hardware; the current Rockwell lifecycle page lists the catalog as discontinued.
Before installation or replacement, verify the complete nameplate, compatible companion hardware, wiring or network design, saved configuration and commissioning plan.
Availability, condition, price, and shipping time for 1746-NI8 are confirmed during quotation.
