Description
The NI-9212 is a C Series Temperature Input Module manufactured by National Instruments. This module is designed to be compatible with CompactDAQ and CompactRIO systems. It is a versatile piece of equipment indicated by its part numbers 785259-01 and 782975-01, each tailored with specific features to cater to different requirements.
The NI-9212 boasts an impressive measurement accuracy of 0.71 degrees C for the 785259-01 model and 0.39 degrees C for the 782975-01 model. This high level of accuracy ensures precise temperature readings, making it ideal for a wide range of applications.
Channel-to-channel isolation is another critical specification of the NI-9212. For the 785259-01 model, the isolation is rated at 60 Vrms, while the 782975-01 model significantly increases this isolation to 250 Vrms. This feature is crucial for safety and functionality when working in environments with high voltages.
The module also differs in its front connectors; the 785259-01 model uses a mini-TC connector, whereas the 782975-01 model employs a more robust Screw Terminal. This difference allows users to choose the model that best fits their connection needs.
With 8 isolated thermocouple channels, the NI-9212 is capable of handling multiple temperature inputs simultaneously. It supports a maximum sample rate of 95 S/s/channel, enabling it to capture fast-changing temperatures accurately.
The module is hot-swappable, allowing for easy replacement or upgrading without the need to power down the entire system. This feature significantly reduces downtime and increases productivity.
The maximum voltage range that the NI-9212 can handle is ±78.125 mV, which, combined with its 24-bit analog to digital converter resolution, ensures detailed and accurate temperature readings.
