National Instruments 777475-01 Multifunction I/O Device

The part number 777475-01 from National Instruments is the identifying part number for the PCI-6110 Multifunction I/O Device. This device features 4 pseudodifferential input channels. These inputs have a 12-bit resolution ADC, which ensures accurate signal representation. The input ranges are programmable with options including ±0.05 V, ±0.1 V, ±0.2 V, ±0.5 V, ±1 V, ±2 V, ±5 V, and ±10 V, providing flexibility to accommodate different signal levels. The maximum sampling rate for the analog inputs is 5 MS/s while its minimum sampling rate is 1 kS/s, making it suitable for a wide range of applications. The 777475-01 has an input coupling of AC or Dc with a maximum working voltage of 20 mV to 10 V for 0 to 3 input channels. It is equipped with overvoltage protection of ± 42 V with all positive and negative input channels protected. It also features FIFO buffer size of 8,192 samples and data transfer methods of DMA, interrupts and programmed I/O.

The device also includes two Volts analog output channels with a 16-bit DAC resolution. The output range is fixed at ± 10 V. The analog outputs can be used for signal generation or control applications where precise voltage levels are required. The 777475-01 Multifunction I/O Device is equipped with 8 lines of digital I/O. Each line can be individually configured for input or output, providing flexibility for various digital control and monitoring applications.

The 777475-01 module requires a power of 2.5 A at +5 VDC with +4.65 to +5.25 VDC at 1 A available at the I/O connector. Its physical dimensions are 31.2 cm by 10.6 cm (12.3 in. by 4.2 in.) making it compact. It is equipped with 68-pin male SCSI-II type I/O connector that allows it to integrate into other digital devices. It has a working temperature of 0 to 45 degrees Celsius and storage temperature of -20 to 70 degrees Celsius with a relative humidity range of 5% to 90%, noncondensing.

The 777475-01 includes two 24-bit counters/timers that can be used for various timing and measurement functions such as frequency measurement, event counting, and pulse generation. The counters support both edge counting and pulse width measurement. The device also features an onboard programmable interval timer that can generate precise timing signals for synchronizing data acquisition tasks.
