The National Instruments part number 783631-01 designates the PXIe-6345 Multifunctional I/O Module, designed for advanced data acquisition and control applications. This versatile module supports 40 differential analog input channels or 80 single-ended channels, boasting an input impedance exceeding 10 GΩ combined with 100 pF between the analog input and ground in the ON state. The integrated 16-bit analog-to-digital converter achieves a maximum sampling rate of 500 kS/s, whether in single-channel or multichannel configurations. The module is equipped with a comprehensive analog triggering system that includes Start, Reference, and Pause triggers, along with Sample and Convert clocks, ensuring precise control over signal timing. It provides two analog outputs, each with 16-bit digital-to-analog conversion capabilities, delivering high fidelity and maintaining a Differential Nonlinearity specification of ±1 Least Significant Bit (LSB) to ensure accuracy in signal generation. The PXIe-6345 also offers 24 digital input/output channels, organized into 8 channels labeled P0.<0..7> and an additional 16 channels distributed across PFI<0..7> and PFI<8..15>. These channels are individually addressable and configurable as either inputs or outputs, facilitating flexible digital signal processing. With built-in input voltage protection, the module is designed to handle voltages up to ±20 V on two pins, ensuring robustness against over-voltage conditions. The recommended operating voltage thresholds for digital signals classify inputs above 2.2 V as "high" and those below 0.8 V as "low." The PXIe-6345 features standard 3U PXI dimensions and weighs approximately 198 g (7.0 oz), combining compactness with high performance. Operating temperature ranges from 0 to 55 ºC, making it suitable for various industrial environments.
