The National Instruments 781057-01 (PXIe-6366) Multifunction I/O Module is a high-performance data acquisition (DAQ) device designed for simultaneous sampling across a broad range of applications. This module features eight differential analog input channels with a maximum sample rate of 2 MS/s per channel and a resolution of 16 bits, ensuring precise signal measurement with reduced loading effects due to its wide input range of ±1 V to ±10 V and high input impedance. Additionally, it includes two analog output channels, also with 16-bit resolution, capable of a maximum update rate of 3.3 MS/s, facilitating accurate control of actuators or the generation of test signals. The integration of advanced timing and synchronization technologies, such as NI-STC3, provides independent timing engines for both analog and digital I/O, making this module particularly suitable for applications in IF digitization, transient recording, and telecommunications testing.

The 781057-01 module is equipped with 24 digital I/O lines and four 32-bit counters/timers, enhancing its versatility for various control and measurement scenarios. The digital I/O functionality supports both static digital input/output and high-speed waveform generation and acquisition, with maximum frequencies reaching up to 10 MHz for PXIe interfaces and 1 MHz for USB connections. It utilizes a 68-pin VHDCI connector and offers compatibility with either PXIe or USB interfaces, depending on the model selected. Built for robust operation in demanding environments, the module includes overvoltage protection and self-resetting fuses.

With the included NI-DAQmx driver, the module simplifies setup and integration into measurement systems, supporting USB 2.0 Hi-Speed or full-speed connectivity while maintaining eight DMA channels for consistent performance across configurations. The USB variant operates within a power supply range of 11 to 30 VDC and has a maximum power consumption of up to 30 W. Secure power connections are facilitated through a 3.5 mm pitch pluggable screw terminal. The standard dimensions of this 3U PXI module are designed for ease of use in a variety of settings, with a weight of 168 g (5.9 oz) and a warranty ranging from 2 to 3 years, ensuring reliability and support for all users.
