National Instruments 780041-01 – Genuine NI Replacement Assembly for Measurement & Control Systems

The NI 780041-01 is an original National Instruments field-replaceable assembly (FRU) used to service or build out NI measurement and control platforms. From my experience, this part number typically shows up in maintenance kits or board-level replacements for NI DAQ, control, or PXI/PCI-based systems. If you’re keeping an installed base running with minimal downtime, this is the kind of OEM piece you want on the shelf—traceable, matched to NI specs, and ready to slot in following the standard NI service procedure.

One thing I appreciate is how predictable these NI assemblies are in the field. They drop in cleanly, pass self-tests in NI MAX in most cases, and help you avoid the guesswork that comes with non-OEM parts. A typical use case is scheduled maintenance on a production PXI rack: you swap the assembly during a planned stop, run a quick self-cal, and the line is back up before the next shift.

Installation & Maintenance

• Environment: Install in a clean, dry cabinet; maintain airflow per NI chassis guidelines. Allow adequate clearance around fans and intake grilles.
• ESD & handling: Use a grounded wrist strap and ESD mat. Keep the assembly in protective packaging until fitted.
• Wiring: Route signal cables away from high‑voltage lines; maintain bend radius and proper strain relief to avoid intermittent faults.
• Procedure: Power down, discharge residual energy, replace the assembly using the NI service guide, and torque mounting screws to spec.
• Post‑install checks: Boot the system, run NI MAX self‑test; perform self‑calibration if supported by the host module.
• Routine maintenance: Quarterly dust removal with dry air, verify fan filters, and keep firmware/driver (NI-DAQmx) current to maintain stability.
