Description
The NI-9210 is a C Series Analog Input module designed by National Instruments, specifically crafted for use with CompactDAQ and CompactRIO hardware platforms. This module, identifiable by its part numbers 784788-01 (Mini-TC) and 785043-01 (Spring Terminal), supports a variety of input types including thermocouples and RTDs. It is distinguished by its ability to offer NIST-traceable calibration, ensuring accurate measurements.
Its isolation levels are noteworthy, with the Mini-TC version offering 60 Vrms channel-to-earth isolation and the Spring Terminal version extending this protection up to 250 Vrms channel-to-earth. The module features four differential analog inputs, utilizing a Delta-Sigma ADC with a resolution of 24 bits. This high resolution is complemented by its scanned sampling mode, which provides a comprehensive data acquisition solution.
The NI-9210 is designed to handle input voltage ranges up to ±80 mV and boasts a conversion time of 70 ms per channel. With an input bandwidth of 15 Hz at -3dB, it ensures high-fidelity signal acquisition. Additionally, the module’s noise rejection capability is excellent, offering a minimum of 85 dB to ensure the integrity of the data collected.
For applications requiring protection against unforeseen voltage spikes, the module offers overvoltage protection of up to ±30 V. It also features internal channels specifically designed to increase accuracy, including an Auto Zero Channel and a Cold Junction Channel. Despite its robust capabilities, the NI-9210 remains energy efficient, consuming 200 mW when active and only 10 mW in sleep mode, making it an ideal choice for a wide range of measurement and monitoring tasks.
