The National Instruments PXI-8250 is a sophisticated PXI System Monitoring Module designed to enhance the reliability and performance of PXI systems. Equipped with six front panel LEDs, this module effectively monitors system voltage, fan operation, and temperature, providing real-time status indicators. The PXI-8250 is compatible with PXI chassis models PXI-1042, PXI-1042Q, and PXI-1045, making it versatile for various applications. It can identify and report issues related to voltage rail anomalies, temperature fluctuations, or fan malfunctions, facilitating proactive maintenance and ensuring optimal functionality. With a built-in relay, the module can trigger alerts when any monitored parameters fall outside predefined operational specifications.

The PXI-8250 allows for simultaneous monitoring of power consumption, fan speeds, and power supply levels, contributing to enhanced system performance reliability. The LEDs indicate system status, illuminating green for normal conditions and red for out-of-range parameters. Additionally, the module features a thermistor that measures the inlet temperature within the power supply shuttle, offering readings within a 0-50 °C range, accurate to ± 1 °C. The RPM of rear fans is also monitored—two fans for PXI-1042 and PXI-1042Q, and three fans for PXI-1045—accurate to ± 50 RPM. Although the PXI-8250 is in a mature status, it remains available for purchase and repair through Apex Waves.
