National Instruments 776910-01

The National Instruments part number 776910-01, also known as the AT-MIO-16XE-50, is a highly versatile multifunction I/O device designed for effective data acquisition across various applications. This ISA-compatible device features 16 analog inputs with 16-bit resolution, enabling sampling rates of up to 20 kS/s, which can also extend to disk streaming at equivalent rates, depending on hard drive performance. The AT-MIO-16XE-50 is equipped with 8 digital I/O channels, 2 analog outputs with 12-bit resolution, and 2 high-resolution 24-bit counter/timers, alongside comprehensive digital triggering capabilities.

As part of the AT E Series, this board offers a Plug and Play-compatible architecture which eliminates the need for traditional configuration methods such as DIP switches or jumpers, significantly simplifying setup and calibration through software. The integration of the National Instruments DAQ-PnP bus interface chip allows for a fully switchless and jumperless design, enabling streamlined software configuration of DMA, interrupts, and base I/O addresses without physical manipulation. Furthermore, the DAQ-STC system timing controller ensures precise control over timing operations, supporting applications like buffered pulse generation and equivalent time sampling.

The 776910-01 features a Real-Time System Integration (RTSI) bus that facilitates synchronization among multiple measurement functions via a single trigger or timing event, allowing for effective communication between up to five DAQ boards within a PC. Additionally, it can be interfaced with a SCXI system to expand input capabilities, accommodating more than 3,000 analog signals from various sources such as strain gauges, thermocouples, and voltage sources.
