Description
The NI-9219 is a universal analog input module designed for versatility and compatibility with NI CompactDAQ or CompactRIO Chassis. It falls under the category of C Series Analog Input and comes in different part numbers including 785994-01, 779781-02, and 192496F-01L. This module is capable of accepting a wide range of input signal types such as strain gages, RTDs, thermocouples, load cells, and powered sensors, making it a flexible solution for various data acquisition needs.
The module offers a channel configuration that is separately selectable for each of its four channels, allowing for a customizable setup to meet specific application requirements. It features a maximum voltage range of ±60 V and a current range of ±25 mA, along with a spring terminal connector type for easy and secure connection. The NI-9219 is designed with safety in mind, offering 250 Vrms channel-to-channel isolation to protect both the module and connected devices from potential electrical hazards.
With a maximum sample rate of 100 S/s per channel, the NI-9219 ensures accurate and timely data acquisition. It operates within a temperature range of -40 °C to 70 °C, making it suitable for use in a variety of environmental conditions. The module is compatible with the NI 9972 Backshell Connector Kit and requires the NI-DAQmx driver software for operation.
The NI-9219 boasts a high-resolution 24-bit ADC, providing precise measurements for all supported input signal types. Additionally, it provides excitation current for all input modes that require excitation, ensuring that sensors and transducers are properly powered for accurate data collection. The module is available in both conformal coated and non-conformal coated variants, with part numbers 779781-02 and 785994-01 respectively, to accommodate different environmental requirements. Calibration services are available and recommended annually or every two years to maintain accuracy and reliability.
