80 analog input channels

National Instruments’

and

are the newest members of the company’s M Series data acquisition (

) family that extend available I/O functionality to include 80 16-bit analog input channels with sampling rates up to 250 kS/s.

The new NI 6225 devices provide the most analog input channels of any NI multifunction DAQ devices and are suitable for applications such as data logging, control and sensor measurements.

The new NI-MCal technology in these devices increases accuracy by performing a self-calibration at each input range and compensating for nonlinearity error, while the NI-STC 2 system controller chip delivers digital I/O and timing capabilities previously unavailable with plug-in DAQ devices, such as timed and correlated digital I/O. The chip also provides 32-bit counter/timers with quadrature encoder inputs and debouncing filters, as well as six DMA channels for dedicated data paths to the PC processor for all I/O operations.

The NI PCI-6225 and PXI-6225 include two analog output channels, 24 digital I/O (DIO) lines, hardware-timed digital I/O at rates up to 1 MHz on eight DIO lines and two 80 MHz, 32-bit counter/timers.
