The National Instruments part number 777484-01 designates the PXI-6040E I/O Terminal, a versatile module designed for high-performance data acquisition. It offers 16 single-ended or 8 differential analog input channels, each configurable via NI-DAQ software to meet specific application needs. The PXI-6040E employs a 12-bit successive approximation analog-to-digital converter (ADC), which allows for a total of 4,096 discrete levels, ensuring precise signal conversion. In single-channel scanning mode, the maximum sampling rate reaches 500 kS/s, while in multiple-channel scanning, this rate is 250 kS/s, divided among the active channels.

The module also includes two analog output channels, featuring a 12-bit digital-to-analog converter (DAC) with the same 4,096 level resolution, facilitating fine control over output signals. It is equipped with a double-buffered, multiplying DAC, which ensures swift and accurate conversion from digital values to analog voltages for smooth output transitions. The PXI-6040E I/O Terminal operates with a +5 VDC power supply, with a tolerance of ±5%, consuming 1.0 A. This power specification excludes any additional draw from the +5 V available at the I/O connector, which supplies between +4.65 VDC and +5.25 VDC at a current capacity of 1 Ampere for connected peripherals. The terminal has a footprint of 16 cm by 10 cm (6.3 in. by 3.9 in.) and weighs 218 g (7.7 oz), making it a compact solution for sophisticated industrial automation applications.
