National Instruments part number 780108-01 refers to the USB-6216 Multifunction I/O Device, an essential tool for diverse test and measurement applications suitable for both academic laboratories and portable data logging scenarios. This compact and portable device features 16 single-ended analog input channels that can be configured as 8 differential channels, providing flexibility for different measurement setups. With a maximum sampling rate of 400 kS/s and 16-bit analog-to-digital (ADC) resolution, the USB-6216 is designed to meet high-precision data acquisition needs. Additionally, the device is equipped with 2 analog output channels and 32 bidirectional I/O channels, enhancing its connectivity capabilities. It features two general-purpose timer/counters with 32-bit resolution, operating at a maximum internal base clock frequency of 80 MHz, along with a frequency generator channel supporting base clocks of 10 MHz and 100 kHz. Designed for rugged applications, the device can withstand continuous voltages of up to 60 VDC between the channel and earth ground and handle overvoltage conditions of 1,000 Vrms for a duration of 5 seconds. As a bus-powered device, the total current draw from its +5 V terminals and digital outputs is capped at 50 mA; should this limit be exceeded, the device intelligently reduces voltage across these outputs to protect against potential damage. The USB-6216 is available in various configurations, each assigned a unique part number, with part number 780108-01 specifically featuring screw terminal connectors. Other configurations, such as part numbers 781004-01 and 780170-01, utilize BNC and SCSI connectors respectively.
