National Instruments 777640-01 Multifunction I/O Device

The part number 777640-01 from National Instruments is the identifying part number for the AT-MIO-16DE-10 Multifunction I/O Device. This device comprises 16 single-ended or 8 differential analog input channels with a 12-bit ADC resolution. It features a maximum sampling rate of 100 kS per second and a streaming-to-disk rate of 100 kS per second. It offers various input signal voltage ranges of 20 V, 10 V, 5 V, 2 V, 1 V, 500 mV, 200 mV, and 100 mV. Its input coupling is DC, with a maximum working voltage of ±11 V of ground. It has a protective feature that includes protection from voltages up to ±35 V when powered ON and  ±25 V when powered OFF. This feature enables the 777640-01 to be protected from potential harm and so maintains the efficiency and reliability of the I/O device.

The Multifunction I/O Module includes 2 voltage analog output channels with a 12-bit resolution of double-buffered DAC capable of generating signals at a maximum update rate of 100 kS per second. Its data transfer methods are DMA, interrupts, and programmed I/O with single transfer, and demand transfer DMA modes. These output channels have a voltage output range of 0 to 10 V with a low output impedance of 0.1 Ω max and a short circuit to ground protective feature. The 777640-01 also attributes to 2 digital triggers required for the Start and stop trigger, gate, and clock for analog inputs while for analog outputs Start trigger, gate, and clock. It is 5V/TTL compatible and has a minimum pulse width of 10 ns.

To operate this module, a power of 0.7 A at +5 VDC is required with the power availability of +4.65 to +5.25 VDC, 1 A at the I/O connector. Physically, this multifunction device has a compact structure with dimensions of 33.8 cm by 9.9 cm (13.3 by 3.9 in) and weighs 830 grams. It also comes with a 100-pin female 0.050 D-type I/O connector that allows easy integration into other digital devices.

This 777640-01 multifunction I/O device is designed to operate at an ambient temperature of 0 degrees Celsius to 55 degrees Celsius with a storage temperature of -20 degrees Celsius to 70 degrees Celsius and has a relative humidity of 10% to 90%, noncondensing.
