The National Instruments 777835-01 is a versatile DAQ device, specifically designated as the PCI-7030/6040E. This model features 16 analog input channels and 2 analog output channels, along with 8 digital input/output lines. It operates at a single PID loop rate of 1 kHz and is powered by a dedicated onboard processor, ensuring real-time, reliable, and deterministic I/O suitable for measurement and control applications. With its 12-bit resolution, the device utilizes a successive approximation ADC that supports DC coupling and incorporates a built-in overvoltage protection of 25V, enhancing the resilience of the daughter board.

The PCI-7030/6040E supports a sampling rate of up to 500 kS/s for the analog inputs, which can be configured as either 8 dual-ended or 16 single-ended channels, and provides a voltage input range of ±0.1 to ±10 V. The two analog outputs are capable of delivering signals across a ±10 V range, with a 12-bit resolution and a maximum sampling rate of 1 MS/s. Additionally, this DAQ device is equipped with two 24-bit counters/timers, leveraging a 133 MHz AMD 486 DX5 processor architecture, facilitating integration of real-time control tasks with various measurement devices on a single host machine. Notably, the system remains operational even in the event of software failure, automatically reconnecting when the host machine becomes accessible again. The 777835-01 operates with the NIDAQmx driver software, compatible with LabVIEW, LabWindows/CVI, and Measurement Studio. Although National Instruments has declared this device obsolete, it is still available through Apex Waves for purchase and repairs.
