Honeywell 51309228-300 Filler Panel for Control Rack Slot Management

The 51309228-300 filler panel closes unused slots in Honeywell card cages and control racks. This accessory blocks dust and debris from entering empty backplane positions. Maintenance teams use it to maintain airflow balance across populated rack sections.

Physical Dimensions and Weight

The 51309228-300 stands 178 mm tall and 40 mm wide at the faceplate. Its body extends 15 mm behind the front panel. The panel weighs only 0.15 kg, which keeps shipping costs low and handling simple.

Interface and Mounting Points

This panel secures to the card cage through 2 captive thumbscrews at the top and bottom edges. The 51309228-300 needs no backplane connector because it carries no electrical function. Consequently, technicians install or remove it in seconds without tools. A blank faceplate surface accepts asset labels and slot identification stickers.

Component Count and Build

Each 51309228-300 consists of 1 aluminum faceplate, 1 mounting flange, and 2 captive thumbscrews. The extrusion measures 1.5 mm thick for rigidity without excess weight. Furthermore, 4 ventilation slots along the lower edge maintain internal rack airflow.

Energy Storage and Power Parameters

The panel houses no circuitry and stores no energy. Instead, the 51309228-300 simply shields empty slots from particulate contamination. It draws zero current from the backplane supply rails. Therefore, the unit adds no load to rack power budgets or thermal calculations.

Key Technical Parameters

Integration Notes

The 51309228-300 fits any open slot in compatible Honeywell card cages. Technicians tighten the two thumbscrews by hand for a secure fit. Additionally, the ventilation slots preserve airflow patterns across adjacent populated modules.
