The National Instruments PXI-1000B is a robust 8-slot PXI chassis designed for 3U modules, featuring one controller slot and seven peripheral slots, each with a cooling capacity of 20 watts. This chassis incorporates a removable modular power supply and includes over-current protection with a push-reset circuit breaker. Users can select between fan speeds to optimize for quiet operation or maximum cooling as needed. The PXI-1000B supports universal input voltages and offers auto-frequency and auto-voltage ranging, making it versatile for various applications. It supplies up to 300 watts of usable power, with 150 watts available for DC-capable devices.

This model’s backplane is interoperable with standard CompactPCI and PXI-compatible products, facilitating easy integration into existing systems. It features three controller expansion slots, allowing for efficient use of peripheral slots and potential left-bound expansion of the system controller. The chassis supports eight PXI trigger lines that can synchronize operations among different PXI-based peripheral modules.

The PXI-1000B typically comes with an AC input power supply, suitable for an input voltage range of 90 to 264 VAC and a frequency range of 47 to 63 Hz. It is also available with a combination of AC and DC input options under part number 777551-11. Additional features include integrated cooling fans, ensuring forced air cooling in both high and low modes, and a 9-pin D-SUB rear connector for enhanced connectivity. The unit measures 15.9 x 10.6 x 7.0 inches and weighs 19 pounds, with a recommended operating temperature range of 0° to 50°C and a storage temperature range of -20° to 70°C. Although the PXI-1000B has been declared obsolete by National Instruments, it remains available for purchase and repairs through Apex Waves.
