The National Instruments PCI-6224, part number 779067-01, is a 16-bit multifunction data acquisition device within the M Series. This versatile DAQ features 32 analog input channels, configurable as 16 differential or 32 single-ended inputs, and is capable of acquiring samples at rates up to 250 kS/s in single or multichannel mode. The device includes 48 digital input/output (I/O) channels, which operate at 5 volts and include 16 programmable function input (PFI) lines. Each PFI input is equipped with a programmable debouncing filter that users can enable or disable based on their requirements.

For connectivity, the PCI-6224 is designed with two 68-pin VHDCI female connectors, ensuring easy access to all channels. The digital I/O signals are protected against under voltage, overcurrent, and electrostatic discharge (ESD) events, enhancing their reliability in various applications. By default, all digital I/O and PFI channels are configured as high-impedance inputs, but users can configure power-up states using NI-DAQmx to specify a desired initial value.

The PCI-6224 supports synchronization capabilities through an RTSI bus and various routing configurations, making it suitable for a wide range of applications. This device is designed for plug-and-play operation with a jumperless setup, allowing the operating system to automatically assign base addresses. While the PCI-6224 has been designated as a legacy product by National Instruments, it remains available for purchase and repair through Apex Waves.

Technical specifications for the PCI-6224 include a compact form factor of 3.8 inches by 6.1 inches and a weight of 0.22 lb. The device operates with power requirements of +5 V, +3.3 V, and +12 V, consuming 0.02 A, 0.25 A, and 0.15 A respectively.
