NI SCXI-1104C

Product introduction

The NI SCXI-1104C is a sophisticated signal conditioning module developed by National Instruments (NI), a trusted name in the realm of test, measurement, and automation. As an integral part of the SCXI (Signal Conditioning eXtensions for Instrumentation) platform, the SCXI-1104C is engineered to elevate the precision and reliability of data acquisition systems. With 4 differential or 8 single – ended input channels, it offers the flexibility needed to adapt to diverse measurement setups.

Capable of handling input voltages within the ±10 V range, the NI SCXI-1104C can interface with a wide array of analog signal sources. Its high – bandwidth performance, reaching up to 100 kHz, ensures that even high – frequency analog signals are accurately conditioned. The 250 V rms channel – to – channel and channel – to – ground isolation feature provides robust protection against electrical interference, guaranteeing stable and precise signal conditioning. This makes the SCXI-1104C an indispensable component for accurate data acquisition in various fields such as industrial automation, scientific research, and product testing.

Core advantages and technical highlights

Adaptable Channel Configuration: The NI SCXI-1104C‘s ability to configure 4 differential or 8 single – ended input channels gives engineers and researchers great flexibility. In scenarios where strong electrical noise is present, the differential input mode can effectively reject common – mode interference, ensuring the integrity of the measured signals. On the other hand, for applications with less complex signal sources and lower noise levels, the single – ended mode provides a simpler and more cost – effective solution.

Exceptional Signal Isolation: The 250 V rms isolation offered by the SCXI-1104C is a key strength. In industrial environments filled with electrical disturbances, this isolation feature acts as a shield, preventing unwanted electrical interference from corrupting the measurement signals. It safeguards the accuracy of the acquired data, enabling reliable decision – making in process control and quality assurance applications.

High – bandwidth and Precision: With a bandwidth of up to 100 kHz, the NI SCXI-1104C excels at conditioning high – frequency analog signals. This makes it well – suited for applications like dynamic vibration monitoring, where rapid changes in signal amplitude need to be accurately captured. The module’s precision in signal conditioning ensures that the measured data truly reflects the physical phenomena being monitored, providing valuable insights for system optimization and fault diagnosis.

Seamless System Integration: As part of the NI SCXI platform, the SCXI-1104C integrates effortlessly with other NI products. Leveraging NI – specific communication protocols, it enables straightforward setup and control within larger measurement and automation systems. This seamless integration streamlines system design, reduces development time, and enhances overall operational efficiency.
