The Bently Nevada 128276-01 is a half-height future expansion faceplate made for the 3500 series machinery monitoring racks—smaller in size than full-height covers, it’s designed to fill half-height empty slots in the rack.
It’s a practical component for setups where you want to leave room for future upgrades: when a 3500 rack has half-height slots not yet used (for smaller I/O modules), this faceplate blocks dust, dirt, and moisture from getting in—critical in industrial spots like refineries or power plants, where harsh debris can damage the rack’s internal parts. It also keeps the rack looking neat and helps maintain steady airflow, which is key to keeping installed modules cool and working reliably.
Since it’s built for future expansion, you can pop it off easily later when you need to add half-height 3500 series modules—no tools or rack modifications needed. It fits perfectly with Bently Nevada’s 3500 rack specs, so there’s no loose gap that could let debris slip through. Whether you’re setting up a new 3500 system or updating an old one, this 128276-01 faceplate keeps the rack protected while keeping space open for later upgrades.
