The National Instruments PCI-6280 is a multifunction data acquisition (DAQ) card designed for PCI slots, providing a cost-effective yet reliable solution for various industrial and research applications. This M Series device, available under part numbers 779108-01 and 191342E-04L, supports both SCC and SCXI signal conditioning modules for versatile measurement configurations. The PCI-6280 features 16 analog input channels, configured as eight differential inputs with an 18-bit resolution and a maximum sampling rate of 625 kS/s. It supports input voltage ranges from +10 V to +0.1 V, with built-in overvoltage protection allowing it to withstand inputs up to +25 V. The device includes an analog trigger with ±1% accuracy and a 10 kΩ input impedance, and the channels are DC-coupled for reliable signal processing. In addition to the analog inputs, the PCI-6280 offers 24 digital I/O channels, each of which can be independently configured as input or output. Two 32-bit general-purpose counters/timers are integrated, offering both internal and external base clock options, while a frequency generator with 50 ppm base clock accuracy is also included. The PCI-6280 utilizes a 68-pin VHDCI connector for I/O connections and is compatible with the NI-DAQmx driver software for straightforward configuration and measurement tasks. The device operates on a power supply of +5 V, +3.3 V, +12 V, and -12 V. Measuring 4.2 in. by 6.1 in. and weighing 0.33 lb., it is compact and easy to integrate into existing systems.
