The National Instruments 784813-01, also known as the PXIe-4310, is a state-of-the-art channel-to-channel isolated analog input module designed for precision voltage measurements. Featuring an impressive 16-bit ADC resolution, this module is equipped with eight differential channels that facilitate accurate data capture across multiple input ranges, including ±10 V, ±5 V, ±2 V, and ±1 V. Each channel supports a maximum sampling rate of 400 kS/s, ensuring rapid data acquisition suitable for diverse applications. The module incorporates software-selectable lowpass filtering options, including 10 kHz, 100 kHz, or a bypass mode, utilizing a 2nd order Butterworth filter to maintain signal integrity with a consistent -3 dB bandwidth of 950 kHz. With a high common-mode rejection ratio (CMRR) of 130 dB at 60 Hz, the NI 784813-01 effectively minimizes interference in noisy environments.

Designed with robust fault protection capabilities, this module tolerates ±60 V between analog input pins and between any AI and COM pins, while also accommodating digital PFI inputs with high voltages up to 5.5 V and low voltages down to 0 V. It features adjustable debounce filters for optimizing triggering conditions and supports a variety of digital and analog triggers, enhancing timing and synchronization flexibility. Housed in a compact 3U PXI Express form factor measuring 16 cm by 10 cm (6.3 in. by 3.9 in.) and weighing only 170 g (6.0 oz.), the 784813-01 is engineered for operation in demanding environments within a temperature range of 0 °C to 55 °C and withstands shocks up to 30 g. This module is suitable for both laboratory and field applications, meeting stringent environmental compliance standards such as IEC, EN, and MIL-PRF certifications. The flexibility of the NI-DAQmx driver simplifies hardware configuration and enhances overall measurement efficiency, making the NI 784813-01 an essential component for high-precision industrial automation and control systems.
