Overview
The Allen-Bradley 1746-N2 is a SLC 500 modular card slot filler used to cover all unused slots in SLC 500 chassis. This slot filler prevents defects in the backplane by helping to keep debris from falling into unused slots and protects those slots from dust. Each unit serves as a protective placeholder and ensures proper spacing and alignment within your SLC control system.
Key Features
- Used to fill empty slots in SLC control systems and serves as a placeholder to ensure proper spacing and alignment of other modules
- Tested to meet EN 61131-2 Programmable Controllers requirements and Directive 73/23/EEC of the Low Voltage Directive Board
- Protects unused slots from environmental contamination
- Suitable for use in Class I, Division 2, Group A, B, C, D, and non-hazardous locations
- Easy installation in SLC 500 chassis slots
