National Instruments 778646-01 PXI Filler Panel
The 778646-01 is an all-encompassing PXI filler panel kit developed for use with National Instruments' 18-slot PXI chassis. Seven of the included panels are individual slot filler panels, one is a double slot filler panel, and two are four-slot filler panels. The purpose of this 778646-01 kit is to physically slot filler panels into your system's slot filler panels, ensuring that four-slot lots will allow uncontrolled airflow into the system. Filling each open bay with the appropriate size of the kits fills voids in the system. It also ensures proper structural support and preserves airflow pathways inside the measurement and automation platform.
The main purpose of the NI 778646-01 is to increase the effectiveness of both the cooling systems and thermal management systems for PXI systems. As you install the kit into the empty bays of your chassis, this will stop the circulation of heated air throughout your chassis and allow for better airflow when using a fan-based cooling method. This is very important because the longevity of active components in your PXI modules can be directly related to the effective functioning of these systems. In addition, the National Instruments 778646-01 also helps ensure compliance with electromagnetic compatibility standards by minimizing radiation and shielding unwanted signals from entering your chassis via open slots. Engineers have found that using the National Instruments 778646-01 is a common practice among those who want to achieve robust thermal and electrical performance on their test equipment.
As part of real-world industrial test and automation configurations, the part is used primarily to configure 18-slot PXI chassis for use in large-scale data acquisition and control applications. While most PXI chassis come with a standard set of basic filler panels, the National Instruments 778646-01 contains additional filler panels required to completely close off many unused spaces in sparsely populated racks. This kit ensures that the chassis complies with thermal requirements, which reduces the likelihood of unscheduled shutdowns and measurement drift due to excessive heat. To the automation professional, the NI 778646-01 is a cost-effective way to help ensure the reliability of high-density PXI test systems.
