Description
The PCI-4451 is a legacy DAQ device with a part number of 185014A-01 (777534-01). It falls under the category of Legacy DAQ Devices, indicating that it is part of a group of devices that were pivotal in earlier data acquisition systems but are now considered to be in the obsolescence phase of their product lifecycle. However, it is important to note that this device is still available for purchase and repairs by Apex Waves, despite its obsolete status announced by National Instruments.
This device features 2 input channels and 2 output channels, providing a balanced approach for both inputting and outputting signals. It boasts a dynamic range of 90 dB, ensuring high-quality signal processing capabilities. The amplitude flatness is maintained at ±0.1 dB (DC to 95 kHz), highlighting the device’s ability to maintain a consistent amplitude across a wide frequency range.
The highest Total Harmonic Distortion (THD) is -90 dB at 1 kHz, while the lowest THD is -80 dB at higher frequencies, indicating the device’s proficiency in minimizing signal distortion across various frequencies. The PCI-4451 utilizes a Delta-Sigma converter type and has a 16-bit resolution, ensuring accurate and precise data conversion.
With sampling rates ranging from 5.0 to 204.8 kS/s, this device can cater to a wide range of data acquisition needs, from slow to fast signal capturing. The available coupling types are AC/DC, providing flexibility in signal coupling based on the application requirements. Furthermore, it supports multiple-board synchronization, allowing for the synchronized operation of multiple PCI-4451 boards within the same system.
The device also includes 8 5V TTL/CMOS digital I/O lines, expanding its versatility in interfacing with various digital devices and systems. This feature enhances the PCI-4451’s utility in complex data acquisition and control applications.
