Description
The PXI-6251 is a multifunction DAQ device belonging to the category of PXI Multifunction DAQ with part numbers 779631-01, 191325F-13L, and 779117-01. This device offers a versatile range of input and output capabilities, making it suitable for a wide array of data acquisition tasks.
For analog input, it features 16 channels that can be configured as either 8 differential or 16 single-ended channels, providing flexibility in connecting to various sensors and signals. The analog inputs boast a resolution of 16-bit, ensuring high precision in measurements. In addition to analog inputs, the device is equipped with 24 digital I/O channels and 2 analog outputs, expanding its utility in controlling and interfacing with external devices.
The PXI-6251 utilizes a 1 68-pin VHDCI I/O connector for connecting to external equipment. To maximize signal integrity and reduce noise, it is recommended to use a 2 m shielded SHC68-68-EPM Cable. For easy and secure connections to sensors and actuators, the SCB-68 Spring-Screw terminal block is recommended.
Software compatibility is essential for seamless integration and operation. The PXI-6251 is compatible with the NI-DAQmx drivers, offering a comprehensive and user-friendly interface for configuring and controlling the device. However, it is important to note that it is not compatible with NI-DAQ Legacy driver software, which may affect its integration into existing systems relying on those drivers.
Maintaining the accuracy and reliability of the PXI-6251 is crucial. It is recommended to calibrate the device at least once every 2 years. Before using the device for critical measurements, a warm-up time of 15 minutes is recommended to ensure stable operation. The device is designed for use in a variety of environments, with an operating temperature range of 0 °C to 55 °C. Despite its robust capabilities, the PXI-6251 remains lightweight at 7.8 oz, enhancing its portability and ease of installation
