National Instruments sbRIO‑9220 C Series Voltage Input Module

The National Instruments sbRIO‑9220 (Part Number: 787814-01) is a CompactRIO-compatible module intended for use in voltage measuring applications. With a high common-mode voltage range of -10 V to 10 V, it provides NIST-traceable calibration and differential analog input capabilities. It guarantees accurate readings with a maximum sample rate of 100 kS/s per channel and 16-bit analog input resolution.

In high-voltage situations, the sbRIO‑9220 guarantees safety and noise immunity with its channel-to-earth ground double isolation barrier. Spring terminals are used in its front connection type to facilitate simple and safe wiring. By enabling simultaneous sampling over all channels, the module improves data acquisition activities' efficiency. The sbRIO-9220 is a non-enclosed, compact design that offers flexibility in system integration and is appropriate for OEM applications. It protects against potential electrical risks with 250 Vrms channel-to-earth ground isolation. The sbRIO-9220's C Series Voltage Input Module improves voltage measurement even further. It allows for flexible data collection in industrial environments with its 16 analog input channels and ±10 V input voltage range.

Accurate and dependable measurements are guaranteed by the module's successive approximation register (SAR) design and 16-bit ADC resolution. It protects against unanticipated signal spikes and connection faults with its overvoltage protection up to ±30 V. To further reduce interference and maintain signal integrity, the C Series Voltage Input Module provides isolation between channels, COM, and earth ground. Its low power consumption—a maximum of 1 W in active mode and 4 mW in sleep mode—contributes to its energy efficiency.

Operating within a broad temperature range of -40 °C to 70 °C, the sbRIO-9220 is well-suited for demanding industrial settings. When operating, it can tolerate humidity levels between 10% and 90% RH, and when stored, it can survive humidity levels between 5% and 95% RH. Safety standards are satisfied by the module's transient overvoltage protection of up to ±30 V and its 250 V RMS channel-to-earth ground isolation.
