National Instruments 777484-01 I/O Terminal
The part number 777484-01 from National Instruments is the identifying part number for the PXI-6040E I/O Terminal. This module features 16 single-ended channels or 8 differential analog input channels. Users can individually configure each channel using NI-DAQ software. The 777484-01 I/O Terminal utilizes a successive approximation type of analog-to-digital converter (ADC). The resolution of the ADC is 12 bits, with 1 in 4,096 levels indicating the number of discrete steps the ADC can represent in converting an analog input signal into a digital value. A 12-bit resolution provides a total of 4,096 discrete levels, providing higher resolution signal conversion.
For single-channel scanning, the maximum sampling rate is 500 kS/s at which the module can sample analog input signals when scanning one channel at a time. For multiple-channel scanning, the maximum sampling rate is 250 kS/s. This rate applies when the 777484-01 I/O Terminal scans multiple channels simultaneously, dividing the total sampling rate among the active channels.
The 777484-01 I/O Terminal features 2 analog output channels. The resolution of the digital-to-analog converter (DAC) at the output is 12 bits, with 1 in 4,096 levels. This means each output channel can represent analog voltages with a granularity of 1 part in 4,096, providing fine control over the output signal. The DAC type featured in 777484-01 is double-buffered, multiplying DAC. This type of DAC typically provides fast and accurate conversion of digital values to analog voltages, and the double-buffered configuration ensures smooth transitions between output updates.
The 777484-01 I/O Terminal requires a +5 VDC power supply with a tolerance of ±5%. It draws a current of 1.0 A from this power source. The power requirement excludes power consumed through the +5 V available at the I/O connector indicating that the specified power draw does not include any additional power drawn from peripherals connected to the I/O connector. The power available at the I/O connector ranges from +4.65 volts DC to +5.25 volts DC at 1 Ampere. This power supply option provides flexibility for peripherals or external devices connected to the I/O terminal. The terminal measures 16 cm × 10 cm (6.3 in. × 3.9 in.) and weighs 218 g (7.7 oz).
