National Instruments PXIe-4302 PXI Analog Input Module

The PXIe-4302 (Part Number: 783865-01) is a high-performance Analog Input Module from National Instruments. Equipped with a 96-pin male DIN I/O connector, this module is able to carry out various measurements with incredible accuracy. The PXIe-4302 features 32 analog input channels which allow the module to handle differential analog signals with simultaneous sampling. Boasting a Delta-Sigma ADC with 24 bits of resolution and a sample rate range of 1 S/s to 5 kS/, this analog input module is an excellent choice for a wide range of test and measurement applications.

One of the standout features of the NI PXIe-4302 is temperature stability, which increases the measurement accuracy of the device. At 10 V, the gain stability of the input module is 8 ppm/°C with an offset stability of 31 μV/°C. When the range is at 100 mV, the gain stability measures 10 ppm/°C with an offset stability of 0.76 μV/°C.

The PXIe-4302 analog input module provides a DC input coupling mechanism in addition to a FIFO buffer capable of retaining 1,023 samples at a time. The I/O of the module is programmed specifically for data transfer, which can be achieved with the help of a SIrect Memory Access (DMA) mechanism. For added security, the NI PXIe-4302 includes fault protection, safeguarding the device whether it is on or off.

In terms of power requirements, the NI PXIe-4302 draws in 1.1 A of power for a rail of 3.3 V, while a rail of 12 V draws 1.3 A. National Instruments recommends that the NI PXIe-4302 is calibrated once a year in order to maintain accuracy and performance.

Physically, the PXIe-4302 device weighs in at 156 g (5.5 oz) and measures 16 cm × 10 cm (6.3 in. × 3.9 in.) in dimensions. It has an operating temperature range of 0 °C to 55 °C with a humidity range of 10% to 90% (relative, noncondensing). When not operational, the NI PXIe-4302 can be safely stored in temperatures ranging from -40 °C to 71 °C with a relative and noncondensing humidity range of 5% to 95%,
