The National Instruments part number 777475-01, known as the PCI-6110 Multifunction I/O Device, is a versatile solution designed for a broad range of data acquisition and control applications. This device accommodates four pseudodifferential input channels featuring a 12-bit resolution analog-to-digital converter (ADC), ensuring precise signal representation. Its programmable input ranges of ±0.05 V, ±0.1 V, ±0.2 V, ±0.5 V, ±1 V, ±2 V, ±5 V, and ±10 V provide flexibility for various signal levels. The PCI-6110 supports a maximum sampling rate of 5 MS/s and a minimum of 1 kS/s, making it capable of handling diverse data rates effectively. Input coupling options include both AC and DC, with a maximum working voltage of 20 mV to 10 V, and the device is safeguarded with overvoltage protection of ±42 V across all input channels.

In addition to its analog capabilities, the PCI-6110 integrates two 16-bit digital-to-analog output channels with a fixed output range of ±10 V, suitable for precision signal generation and control applications. The module also features eight lines of digital I/O, which can be individually configured, enhancing its flexibility for digital control and monitoring tasks. The device’s FIFO buffer size is 8,192 samples, and it offers multiple data transfer methods, including DMA, interrupts, and programmed I/O.

The PCI-6110 operates on a power supply requirement of 2.5 A at +5 VDC, with additional +4.65 to +5.25 VDC at 1 A available at the I/O connector for interfacing with other devices. Compact in design, the module measures 31.2 cm by 10.6 cm (12.3 in. by 4.2 in.) and connects via a 68-pin male SCSI-II type I/O connector. It is suitable for use in environments with operating temperatures ranging from 0 to 45 degrees Celsius and storage temperatures from -20 to 70 degrees Celsius, with a relative humidity tolerance of 5% to 90%, non-condensing. The PCI-6110 also includes two 24-bit counters/timers, ideal for timing and measurement functions such as frequency measurement and pulse generation, supported by an onboard programmable interval timer for precise timing signal generation.
