Engineered for precision and reliability, the SCXI-1520 from National Instruments is a versatile signal conditioning module tailored for industrial control and measurement environments. Designed to integrate seamlessly into SCXI and PXI systems, this module enhances analog signal integrity through advanced amplification and filtering capabilities.
The SCXI-1520 supports 16 single-ended or 8 differential input channels, each equipped with a 20 kHz low-pass filter to reduce noise and interference. This ensures that even in electrically noisy industrial settings, data remains clean and accurate for critical measurement tasks.
With an isolation voltage rating of up to 350 Vrms between channels and ground, the SCXI-1520 provides enhanced safety and signal integrity. This high level of isolation protects both equipment and operators while allowing the module to be used in a wide range of industrial applications, including vibration analysis, temperature monitoring, and process control.
The module features a 16-bit analog-to-digital converter (ADC) with a sampling rate of up to 200 kS/s, enabling high-resolution data acquisition. Its compatibility with SCXI and PXI/CompactPCI chassis ensures straightforward integration into existing test and automation systems, reducing deployment time and complexity.
Built to meet the demands of industrial environments, the SCXI-1520 operates reliably within a temperature range of 0°C to 55°C. It is certified to international standards including CE, UL, and RoHS, ensuring compliance with global safety and environmental regulations.
