Description
The PCI-6250 by National Instruments, with part number 779069-01, is a PC-based Multifunction DAQ device designed to meet a wide range of data acquisition needs. It offers a robust set of features including 16 Analog Input (AI) channels and 24 Digital I/O (DIO) channels. The analog input channels can be configured as either 8 differential channels or 16 single-ended channels, providing flexibility in connection and measurement types.
The device boasts a timing resolution of 50 ns and offers a maximum sampling rate of 1.25 MS/s for single-channel operations, and 1 MS/s per channel in multichannel mode. This high sampling rate is ideal for capturing fast transient signals and for applications requiring high-speed data logging or waveform generation.
It supports a wide input voltage range from +0.1 V to +10 V, with a maximum working voltage of +11V. This wide range allows for the measurement of various signal types without the need for additional signal conditioning. The PCI-6250 is equipped with an Input FIFO of 4095 samples, enhancing data throughput and reducing the risk of data loss during high-speed acquisitions.
The device also features 24 DIO channels, providing ample connectivity for interfacing with external devices, signals, or actuators. Additionally, it includes two general-purpose, 32-bit counters/timers, further extending its utility for complex timing, counting, and pulse generation tasks.
Internal base clocks of 0.1 MHz, 20 MHz, and 80 MHz are available, alongside an external base clock frequency range of 0-20 MHz, enabling precise timing and synchronization for measurement and control applications. The PCI-6250 utilizes NI-MCal calibration technology and the NI-PGIA 2 amplifier, ensuring accurate and reliable measurements.
Software support is provided for NI-DAQmx and NI LabVIEW, facilitating easy integration and development of custom data acquisition and control applications. Despite being announced as a legacy product by National Instruments, the PCI-6250 remains available for purchase and repairs through Apex Waves, ensuring long-term support and availability for existing and new systems.
