Description
The PCI-4451 is a legacy Data Acquisition (DAQ) device, bearing the part number 777534-01. As a part of the legacy DAQ devices category, it is designed to cater to a variety of data acquisition needs. The device is now considered to be in an obsolete status, as announced by National Instruments. However, it remains available for purchase at Apex Waves.
For those looking to upgrade or find a replacement, the recommended successor is the PCI-4551 (part number 777535-01). This model is designed to offer similar functionalities with potentially enhanced features or performance.
The PCI-4451 features 2 input channels and 2 output channels, making it suitable for small to medium scale data acquisition tasks. It supports a sampling rate range from 5.0 to 204.8 kS/s, allowing for flexible data capture speeds depending on the requirements of the application.
With a dynamic range of 90 dB and an amplitude flatness of ±0.1 dB (DC to 95 kHz), the device ensures high-quality signal acquisition and processing. The Total Harmonic Distortion (THD) at 1 kHz is rated at -90 dB, while at higher frequencies, it slightly increases to -80 dB.
The PCI-4451 operates with a 16-bit resolution, providing a good balance between data storage efficiency and signal fidelity. It also offers versatility in signal connection types, supporting both AC and DC coupling. Additionally, the device includes 8 digital I/O lines supporting 5V TTL/CMOS, which allows for further interfacing with external devices or systems.
This DAQ device exemplifies a blend of performance, flexibility, and reliability, making it a valuable tool for a wide range of data acquisition applications, despite its status as a legacy product.
