The NI SCC-SG24 is a 2-channel analog input module for high-precision strain measurement with full-bridge load cells and strain gauges. It delivers clean, accurate data through integrated signal conditioning and a 1.6 kHz low-pass filter, enabling reliable performance in mechanical testing, structural analysis, and process monitoring. The module integrates directly into National Instruments C Series data acquisition systems.
