Main Features and Advantages

High – Channel – Count and Multiplexing Flexibility

The NI NI-9205 stands out with its 16 analog input channels, providing the ability to simultaneously monitor multiple signals. This high channel count is ideal for applications that require the measurement of multiple physical parameters at once, such as in large – scale industrial monitoring systems where numerous sensors need to be connected. Additionally, the software – selectable single – ended or differential multiplexing type offers users the flexibility to configure the module according to their specific application requirements. Single – ended configuration is suitable for applications where a common ground is present and cost – effectiveness is a priority, while differential configuration provides better noise rejection and is suitable for measuring small – voltage signals in noisy environments.

High – Resolution and Accurate Data Acquisition

With a 16 – bit resolution, the NI-9205 ensures accurate analog – to – digital conversion, allowing for precise measurement of input signals. This high resolution enables the module to detect small changes in the input voltage, making it suitable for applications that demand detailed and accurate data. Whether it’s measuring the subtle variations in temperature or pressure, the NI NI-9205 can capture the data with great precision, providing users with reliable information for analysis and control.

Fast Sampling Rate

The module offers a sampling rate of up to 250 kS/s (shared across all channels), enabling it to quickly acquire data from multiple channels. In applications where real – time monitoring of rapidly changing signals is required, such as in vibration analysis or electrical signal monitoring, this fast sampling rate ensures that no data is missed. It allows for the timely capture of transient events and the accurate representation of dynamic signals, facilitating effective analysis and decision – making.

Robust Isolation and Noise Immunity

Equipped with 2500 V rms galvanic isolation, the NI NI-9205 provides excellent protection against electrical noise, ground loops, and voltage spikes. This isolation enhances the reliability of the acquired data by preventing external electrical interference from affecting the signal quality. The high input impedance also helps to minimize loading effects on the sensors, ensuring accurate signal measurement. These features make the module suitable for use in harsh industrial environments and other challenging measurement scenarios where noise immunity is crucial.
