National Instruments 781044-01 Multifunction I/O Device
The 781044-01 from National Instruments is a Multifunction I/O Device that is also known as the PCIe-6321. As part of the X series, the device has a wide range of analog and digital input/output functions and is made for a variety of industrial applications. It is appropriate for a variety of jobs, from simple data logging to intricate automation systems, thanks to its high-performance data acquisition and control capabilities.
With PCI Express connectivity, the 781044-01 utilizes the bus interface's high-throughput capabilities to provide effective data transfer and synchronization. Precise timing operations are guaranteed by its onboard NI-STC3 timing and synchronization technology, which features separate analog and digital timing engines as well as retriggerable measurement duties.
The device's analog input part has 16 single-ended or 8 differential channels with guaranteed no missing codes and 16-bit resolution. With a maximum working voltage of ±11 V, it provides many input ranges (-0.2 V to +10 V). It guarantees precise and dependable analog measurements under various signal situations thanks to its low crosstalk (-90 dB for non-adjacent channels, -75 dB for adjacent channels) and 100 dB CMRR.
The device offers two channels of analog output with 16-bit resolution, which guarantees accurate control and manipulation of analog signals. It restricts glitch energy for smooth signal creation and keeps monotonicity with ±1 LSB DNL.
Through pull-down resistors and input voltage protection integrated in, the 781044-01 provides 24 individually programmable channels for input or output in terms of digital I/O. It facilitates the synchronization of other systems or devices with external digital triggers from many sources.
In addition, the gadget has flexible trigger options for a variety of uses, such as digital waveform production and acquisition, counter and timer capabilities, and analog input/output. It enables trigger bus communication between devices, which makes multi-device configurations easier to synchronize.
Compliant with several slot configurations and featuring a small x1 PCI Express form factor, the 781044-01 provides system integration flexibility. To facilitate various kinds of data collecting and control operations, it offers eight DMA channels for effective data transfer.
