Description
The NI-9219 is a model within the C Series Universal Analog Input category, designed for compatibility with NI CompactDAQ or CompactRIO Chassis. This module is capable of interfacing with various signal types including strain gages, RTDs, thermocouples, load cells, and powered sensors. It features four separately selectable channels, allowing for a versatile range of measurements.
The device comes with part numbers 785994-01, 779781-02, and 192496F-01L, where the 779781-02 model is conformally coated for added protection, unlike the 785994-01 model. It supports an estimation range of ±60 V for voltage and ±25 mA for current, making it suitable for a wide range of applications. The connection type utilized by the NI-9219 is a spring terminal, offering an easy and reliable means of connection.
One of the key specifications of the NI-9219 is its isolation rating of 250 Vrms channel-to-channel (Ch-Ch), ensuring safe and accurate measurements across each of the four channels. The module is capable of a maximum sample rate of 100 samples per second (S/s) per channel, which is facilitated by its 24-bit ADC resolution for high-precision data acquisition.
The operating temperature range of the NI-9219 is from -40°C to 70°C, allowing it to perform reliably in a variety of environmental conditions. To operate, the module requires the NI-DAQmx driver, ensuring seamless integration and compatibility with NI software environments. Additionally, the module features excitation current available for all input modes, enhancing its flexibility for different types of sensors and measurements.
