Product Performance
High precision measurement: With characteristics such as high input impedance and low noise spectral density, it can achieve high-precision amplification and measurement of weak signals, ensuring the accuracy and reliability of collected data. For example, it can provide accurate results when measuring small voltage changes.
Synchronous sampling function: 8 channels can be sampled simultaneously, accurately maintaining the phase relationship between channels. For applications that require monitoring multiple related signals simultaneously, such as multi-channel vibration testing and multi-phase current and voltage measurement in power systems, it can ensure the temporal consistency and accuracy of data collection.
Wide input range and protection: The input range is ± 10V, which can adapt to the output signal amplitude of various sensors; At the same time, it has an overvoltage protection of ± 30V, which can effectively prevent module damage due to sensor failures or unexpected voltage surges, improving the stability and reliability of the system.
Flexible configuration and compatibility: Programmable instrument amplifier gain through DIP switches, which can be flexibly configured according to different sensor outputs and measurement requirements; Compatible with various NI software and hardware products, such as NI DAQmx software, SCXI chassis and other modules, NB series data acquisition boards, etc., making it easy to build complex data acquisition and control systems.
