Description

The Allen-Bradley 1746-N2 is a protective hardware component specifically engineered for the SLC 500 modular chassis system. As a non-electronic slot filler module, it is designed to occupy empty or unused slots within 1746-A4, 1746-A7, 1746-A10, or 1746-A13 chassis. Its primary function is to maintain the mechanical and environmental integrity of the PLC rack assembly by protecting exposed backplane connectors from dust, debris, and physical damage.

Features

  • Contaminant Protection: Prevents dust, metallic shavings, and environmental debris from entering open backplane slots, reducing the risk of short circuits or signal interference.
  • Airflow Management: Helps maintain optimal cooling airflow patterns across the chassis, ensuring active modules operate within their thermal limits.
  • System Integrity: Ensures the chassis assembly complies with safety standards, including EN 61131-2 and the Low Voltage Directive, supporting Class I, Division 2 hazardous location ratings.
  • Compatibility: Designed for universal use across all 1746 SLC 500 modular chassis backplanes.

Installation Guidelines

  • Ensure the chassis power is off before installing or removing any module or filler.
  • Align the 1746-N2 with the card guides of the empty slot.
  • Slide the module into the chassis until it is fully seated against the backplane.
  • Secure the module using the built-in latching mechanism to prevent accidental dislodgement due to vibration.
  • Maintain a clean environment during installation to prevent debris from entering the backplane connectors.

FAQ

Is the 1746-N2 an electronic module?

No, the 1746-N2 is a passive, non-electronic mechanical component. It contains no circuitry and does not require any configuration or software setup.

Why is it necessary to install a slot filler?

Installing slot fillers is essential for maintaining the IP rating of your chassis, preventing the ingress of conductive dust, and ensuring that cooling air is directed through the active modules rather than escaping through empty slots.
