Product Description P/N: 1756-N2
Description
The Allen-Bradley 1756-N2 is a package of two passive slot filler modules designed for unused slots in ControlLogix chassis. Each module occupies a single slot width and contains no electronic circuitry or backplane current draw. The fillers protect exposed backplane circuitry from dust, debris, and industrial contaminants.

Information About 1756-N2
The 1756-N2 is part of the ControlLogix platform and serves as a protective accessory for maintaining the integrity of unused chassis slots. As a passive single-slot module, it mechanically occupies a slot while providing no electrical interface, ensuring the backplane remains shielded in environments with airborne particulates or gaseous contaminants. Slot fillers like the 1756-N2 are commonly used in systems where expansion space is reserved, where module inhibition is implemented, or where staged installation of hardware is planned. The modules can be inserted or removed under power since they contain no active components, simplifying maintenance and system reconfiguration.
Key Features:
- Pack of two modules: Includes two single-slot filler assemblies.
- No electronic circuitry: Zero current draw from the ControlLogix backplane.
- Protects vacant slots: Shields backplane connectors from dust and contaminants.
- Supports expansion planning: Allows reserving slots for future modules.
- Ideal for module inhibition: Maintains configuration without installed hardware.
- Hot insertion/removal: Safe to install or remove while the chassis is powered.
- Standard ControlLogix fit: Matches the mechanical profile of functional modules.
- Wide operating temperature range: Suitable for 0–60°C industrial environments.
- Passive thermal characteristics: Produces minimal heat and dissipates up to 6.2 W.
- No enclosure required: Used directly in ControlLogix chassis slots.
- Durable construction: Designed for long-term use in demanding industrial settings.
The 1756-N2 delivers the reliability and precision required for protecting unused ControlLogix chassis slots in industrial automation systems.
