Description
The National Instruments SCXI-1200 Data Acquisition and Control Module is a versatile device with 12-bit resolution, offering flexibility in data collection through its 8 single-ended or 4 differential analog input channels and 2 single-ended analog output channels. It supports various input modes including Referenced (RSE), Non-referenced (NRSE), and Differential (DIFF), accommodating a wide range of signal types.
Users can implement a unipolar input voltage range from 0 V to 10 V or a bipolar range from -5 V to +5 V, ensuring compatibility with different sensor outputs. The module is equipped with 32 digital I/O channels that are TTL compatible, allowing for extensive digital interactions and control.
Robust overload protection mechanisms are in place, providing ±42 V protection when the device is powered on and ±15 V when it is powered off, safeguarding the module against unexpected voltage spikes. The SCXI-1200 maintains accuracy with an offset error of ±50 mV maximum before calibration and ±0.2 mV maximum after calibration, and a gain error of ±1% before calibration, reducing to ±0.004% of the reading after calibration.
The module’s voltage output range is versatile, offering 0 to +10V and ±5V, which is suitable for a variety of control applications. Finally, the device operates seamlessly with the NI-DAQmx driver software, ensuring easy integration with software packages and application development environments.
