The National Instruments part number 777530-01 identifies the PCI-6111 Multifunction DAQ Device, a versatile solution ideal for sophisticated test and measurement applications that necessitate advanced synchronization. This device is part of the S Series and includes features such as two pseudodifferential analog input channels with a resolution of 12 bits, allowing for an input coupling selection of either DC or AC, and a sampling rate that ranges from 1 kS/s to 5 MS/s. Each analog input channel offers overvoltage protection up to ±42 V, ensuring the safety of both positive and negative inputs, while data acquisition can be facilitated through DMA, programmed I/O, or interrupts due to the onboard FIFO buffer capacity of 8,192 samples.

Additionally, the PCI-6111 is equipped with two voltage analog output channels that provide 16 bits of resolution and a maximum update rate of 4 MS/s for single-channel operations, or 2.5 MS/s when using both channels. These outputs feature a FIFO buffer of 2,048 samples and a voltage output range of ±10 V. The device is further enhanced by eight digital I/O channels compatible with TTL/CMOS technologies, with data transfers governed by programmed I/O. Power consumption for the PCI-6111 is 2.0 A at +5 VDC. Its dimensions are 31.2 cm by 10.6 cm (12.3 in. by 4.2 in.), excluding connectors. Each unit comes with a three-year warranty, reinforcing the quality and reliability expected from National Instruments.
