Description
The 1756-N2 is a slot filler module package manufactured by Rockwell Automation under the Allen-Bradley brand. It belongs to the ControlLogix series of modular programmable controllers. Each package contains two (2) passive slot filler modules designed to cover and protect the exposed backplane circuitry of vacant slots in standard ControlLogix chassis. The module is constructed as a single-slot-width passive cover without any electronic circuitry, and therefore does not occupy a functional slot position or draw current from the backplane.

Product Applications
Physical Installation Steps
Features:
- ControlLogix empty slot cover
- Single-slot chassis filler
- Passive mechanical component
- No power consumption
- Protects unused chassis slots
The module is installed whenever one or more chassis positions are intentionally left empty for future system expansion or when unused slots remain after system configuration. By covering open chassis positions, the 1756-N2 helps reduce the entry of dust, debris, and other contaminants that could affect the ControlLogix backplane and adjacent modules.
The 1756-N2 Allen-Bradley ControlLogix Slot Filler may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
The slot filler also assists in maintaining proper airflow within the chassis and provides additional mechanical protection for exposed backplane connectors. In industrial environments such as manufacturing plants, power generation facilities, oil and gas installations, and process industries, the use of slot fillers helps keep control cabinets organized and protected.
Unlike ControlLogix I/O, communication, motion, or controller modules, the 1756-N2 does not appear in Studio 5000 Logix Designer because it has no electronic identity, requires no configuration, and exchanges no data with the controller. It functions solely as a physical protective cover.

Align the Module: Hold the 1756-N2 vertically and line up the top and bottom plastic circuit guides with the corresponding tracks in the empty chassis slot.
Slide into Chassis: Carefully slide the empty slot cover into the chassis until the rear alignment pins engage with the backplane perimeter.
Seat the Cover: Press firmly on the top and bottom tabs of the module cover until you hear a clean click. This means the locking tabs have locked into the chassis frame.

Technical notes
The 1756-N2 module is a rectangular plastic housing with a front faceplate and rear connector cover. The module features a light gray or off-white upper body with a black lower base section. It is engineered to match the physical form factor of standard ControlLogix I/O modules, ensuring uniform slot coverage and chassis structural integrity. The module installs directly into any empty slot of a standard ControlLogix chassis (1756-A4, 1756-A7, 1756-A10, 1756-A13, 1756-A17 series) without requiring tools.
