National Instruments 777530-01 Multifunction I/O DAQ Device

Part number 777530-01 from National Instruments is the identifying part number for the PCI-6111 Multifunction DAQ Device. This device from the S Series is an excellent choice for any test and measurement application that requires advanced synchronization capabilities; as it comes equipped with analog output, analog input, and digital input/output channels.

The two analog input channels of the 777530-01 are pseudodifferential, with 12 bits of resolution. The input coupling for these channels can be set to either DC or AC, and the sampling rate ranges from 1 kS/s to 5 MS/s. In addition, the analog input channels are covered by overvoltage protection of up to ±42 V.  Both the positive and negative inputs of each channel are protected, and the device includes a FIFO buffer of 8,192 samples. Data transfers through the analog input channels of the 777530-01 can occur through DMA, programmed I/O, or interrupts. 

In addition to the analog input capabilities, the 777530-01 features two voltage analog output channels. These channels boast 16 bits of resolution, a FIFO buffer of 2,048 samples, and a voltage output range of ±10 V. Depending on the system used, the maximum update rate for these channels is 4 MS/s (one channel) or 2.5 MS/s (two channels). 

The 777530-01 also features 8 digital I/O channels which are compatible with TTL/CMOS. The data transfers for these channels are determined through a programmed I/O. 

The amount of power required for the 777530-01 is 2.0 A, measured at +5 VDC. The device measures 31.2 cm by 10.6 cm (12.3 in. by 4.2 in.), not including the connectors.
