National Instruments 777383-01

The National Instruments 777383-01 is a multifunction data acquisition device, specifically the PCI-6040E model, designed to cater to diverse measurement and control applications. This device features 16 analog input channels with a 12-bit resolution, capable of delivering sampling rates up to 500 kS/s for single channels and 250 kS/s for multichannel configurations. Users can also leverage its two analog output channels, which provide 12-bit resolution and a data output rate of 1 MS/s. The 777383-01 ensures high-performance data streaming capabilities to disk, with speeds reaching up to 250 kS/s, depending on hard drive specifications.

Integrating advanced timing functions, the device includes SCANCLK, a software-selectable output signal for clocking external analog input multiplexers following A/D conversions. It generates a pulse with a leading edge occurring 50 to 100 ns after conversion, featuring a pulse width of 400 to 500 ns. Additionally, EXTSTROBE can be configured to generate single pulses or a series of eight pulses in hardware strobe mode, facilitating external device latching or event triggering, with the software controlling the signal levels.

Connectivity is provided through a 68-pin male 0.050 D-type I/O connector, and real-time execution is supported by a dedicated 700 MHz Pentium III processor, along with 32 MB of DRAM for user programs and 32 MB of onboard CompactFlash storage. The device supports a maximum single PID loop rate of 26 kHz, making it a powerful choice for applications requiring precise control and data acquisition. It operates on a +5 VDC power supply, drawing up to 1.0 A, and is compatible with NI-DAQ 7 driver software, ensuring easy integration into existing systems.
