PRODUCT INFORMATION
Product Overview
Revision scope: These specifications describe 1746-N2/A (Series A). Check the corresponding technical data before specifying another hardware series.
The Allen-Bradley 1746-N2 is a card slot filler designed for the SLC 500 control platform. This hardware accessory covers unpopulated module slots in standard modular chassis assemblies. It installs directly into empty rack locations to protect internal backplane connectors from dust and contamination. It also maintains proper airflow pathways throughout the operating chassis enclosure.
This slot filler functions as a passive mechanical dummy module with no active electrical connections. It fits any open standard slot across SLC 500 chassis architectures. Maintenance personnel use this unit to preserve enclosure integrity during progressive system commissioning or phased module replacements. It requires no configuration, software setup, or wiring during installation.
