Part Number: PCI-4552

The National Instruments PCI-4552 is a high-performance Dynamic Signal Acquisition Device designed for precision analog input applications using the PCI bus. It features four analog inputs with a 16-bit resolution and a sampling rate of up to 204.8 kS/s, accommodating an extensive input range of ±10 mV to ±42.4 V. The device supports differential and single-ended input configurations, alongside eight digital I/O channels and functionality for analog and digital triggering.

The PCI-4552 employs differential inputs, allowing users to connect either differential or single-ended signals. When using the BNC-2140 DSA accessory, users can configure the inputs to referenced single-ended (SE) channels, enhancing measurement accuracy by grounding the negative input from floating sources to reduce common-mode noise. The integrated trigger circuit can monitor any of the analog input channels for level triggering, with the trigger level range mirroring the analog input voltage range, maintaining consistent resolution and accuracy.

Compatibility with Traditional NI-DAQ driver software and VirtualBench-DSA enables seamless integration with various programming environments, including LabVIEW, LabWindows/CVI, and Microsoft Visual C++. Configuration and device management are facilitated through the Measurement & Automation Explorer (MAX) tool. The PCI-4552 measures 4.19 x 12.28 x 0.73 inches and operates within a temperature range of 0 °C to +40 °C, with a storage temperature range of -25 °C to +85 °C, and a relative humidity tolerance of 10% to 95%. While the PCI-4552 is listed as obsolete, it remains available for purchase and repairs through Apex Waves.
