Description
The NI-9211 is a high-performance C Series Analog Input module, designated with the part number 779001-01. This module is specifically designed for applications requiring high precision and versatility. It features 4 thermocouple channels, making it ideal for temperature measurements across various environments.
With a sampling rate of 14 Samples per second (S/s) and a 24-bit resolution, the NI-9211 ensures accurate and reliable data acquisition. This module is compatible with both NI CompactDAQ and CompactRIO systems, offering flexibility in system integration.
One of the key features of the NI-9211 includes anti-aliasing filters, cold-junction compensation, open-thermocouple detection, and an autozero function. Additionally, it provides screw terminal connectors for easy and secure connections. The module also boasts dual channel-to-earth ground isolation, enhancing safety and noise immunity.
Driver compatibility is extensive, supporting NI-DAQmx, LabVIEW, LabWindows/CVI, and .NET, thereby allowing easy integration into existing systems or for the development of custom applications. The module’s channel-to-COM safety voltage is rated at +/- 1.5 V, and it features an impressive common-mode rejection ratio of 95 dB (channel-to-common) and 170 dB (common-to-earth ground), ensuring high signal integrity.
The NI-9211 operates in a scanned sampling mode and can measure voltages within a range of ±80 mV, accommodating a wide range of sensor types and signals. Power efficiency is a notable aspect of this module, with a maximum power requirement of 170 mW when active and 4 mW in sleep mode, optimizing both performance and energy consumption for long-term deployments.
