Description
The PCI-6238 is a PC-based multifunction DAQ part number 193190D-01L (779623-01), belonging to the M Series, manufactured by National Instruments. This device is designed for current I/O bank isolation, enhancing its reliability and performance in various applications.
It features 8 AI (Differential current input channels) with an ADC resolution of 16 bits, capable of sampling rates up to 250 kS/s. The input current range is +/-20 mA, with a maximum input impedance of 100 Ω and an overcurrent capability of +/-40 mA. For outputs, it offers 2 AO (Analog current output channels) with a sampling rate of 500 kS/s for a single channel and 450 kS/s per channel for dual-channel operations.
The device is equipped with FIFO buffer memory capable of holding 4095 samples for input and 8191 samples for output, ensuring efficient data handling during high-speed operations. The digital PFI channels include 10 (6 DI, 4 DO), with a digital input range of 0 V to 30 V and an input current of up to 9 mA. Additionally, it includes two 32-bit counters/timers, further expanding its versatility in various data acquisition and control applications.
