PXIe-1082DC

The NI PXIe-1082DC is an 8-slot, high-performance PXI Express chassis designed for applications that require a DC power source. It is the mobile-optimized sibling of the standard PXIe-1082, making it the ideal choice for engineers conducting tests in vehicles, aircraft, or remote locations where AC power is unavailable. With a mix of PXI Express and hybrid slots, it provides a flexible, ruggedized platform for high-speed data acquisition and control in the field.

1. Key Technical Specifications

2. Detailed Technical Breakdown

Native DC Power Integration

The standout feature of the PXIe-1082DC is its ability to run directly off a DC battery or vehicle power system. Accepting a wide input range of 18 VDC to 30 VDC, it handles the fluctuations common in automotive and aerospace electrical systems. This eliminates the need for power inverters, which can introduce electrical noise and reduce overall system efficiency.

Balanced Slot Density and Throughput

The chassis provides 7 peripheral slots in a compact form factor. By utilizing a PCIe Gen 2 backplane, it offers a total system bandwidth of 7 GB/s. The four hybrid slots allow for the use of both PXI Express modules and hybrid-compatible PXI modules, ensuring that you can leverage your existing hardware inventory while upgrading to newer, higher-speed instrumentation.

Ruggedized for Mobility

The PXIe-1082DC is built to withstand the rigors of mobile use. It features a robust mechanical design and high-performance fans that ensure reliable cooling even in constrained environments like a vehicle trunk or an equipment rack on a test track. The integrated 10 MHz and 100 MHz reference clocks, along with PXI trigger lines, ensure that all modules remain perfectly synchronized regardless of the physical vibrations or environment.

3. Usage and Application Scenarios

In-Vehicle Data Acquisition (DAQ)

For automotive engineers performing road tests, the PXIe-1082DC is the standard choice. It can be powered directly from the vehicle’s 24V battery system to collect high-speed sensor data from CAN/FlexRay buses, strain gauges, and accelerometers simultaneously.

Flight Testing and Avionics Validation

In aerospace applications, the 28V DC power rail is standard. The PXIe-1082DC can be integrated into flight-test instrumentation racks to monitor avionics systems and structural integrity during actual flight maneuvers without requiring specialized AC power conversion.

Field Service and Remote Monitoring

Technicians in the oil and gas or renewable energy sectors use the PXIe-1082DC for high-fidelity diagnostics at remote sites. When paired with a battery array or solar power system, it provides a lab-grade measurement platform in a portable, DC-ready package.

4. Product Comparison and Recommendations

• NI PXIe-1082DC (The Mobile Choice): 8 slots, DC-powered. Best for vehicles and remote sites.

• NI PXIe-1082 (The Lab Choice): 8 slots, AC-powered. Identical performance but for standard laboratory environments.

• NI PXIe-1071 (The Compact Alternative): 4 slots, AC-powered. Best for small-scale benchtop setups where space is more critical than slot count.

• NI PXIe-1085 (The Throughput Leader): 18 slots, 24 GB/s. Best for stationary, massive-scale RF and streaming applications.

Summary

The NI PXIe-1082DC bridges the gap between laboratory precision and field-ready mobility.
