198864D-01L

Description

The NI-9211 is a versatile and high-performance C Series Analog Input module, identified by part numbers 198864D-01L and 779001-01. This module is specifically designed to cater to various applications requiring precise temperature measurements through thermocouples. It features 4 thermocouple channels, allowing for multiple points of temperature data acquisition simultaneously.

The NI-9211 operates at a sampling speed of 14 S/s (samples per second) and boasts a high-resolution 24-bit A/D converter, ensuring accurate and reliable data capture. For enhanced connectivity, the module supports multiple communication interfaces including USB, Ethernet, and 802.11 Wi-Fi, providing flexibility in integrating with different systems and networks.

Among its notable features are anti-aliasing filters, which minimize signal distortion; cold-junction compensation, crucial for accurate temperature measurements; open-thermocouple detection, which enhances safety and reliability by detecting disconnected thermocouples; and an autozero function, which helps in minimizing offset errors.

The NI-9211 is engineered with dual channel-to-earth ground isolation, significantly reducing noise and ensuring the integrity of measurement data. This module is compatible with a range of software including NI-DAQmx, LabVIEW, LabWindows/CVI, and .NET, offering users a variety of programming environments to suit their application needs.

It supports a channel-to-COM safety voltage of +/- 1.5 V and has an impressive common-mode rejection ratio (CMRR) of 95 dB (channel-to-common) and 170 dB (common-to-earth ground) across frequencies up to 60MHz, ensuring high resistance against interference and noise in challenging environments. Additionally, the module includes 1 auto-zero channel and 1 cold-junction compensation channel, further enhancing measurement accuracy.
