NI PXIe-7856R
Digital I/O
The NI PXIe-7856R provides connections for 48 digital input/output (DIO) channels.
Connector 0 contains 16 low-speed channels that can run up to 10 MHz signal frequencies and
Connector 1 contains 32 high-speed DIO channels that can run up to 80 MHz signal
frequencies. Each connector has selectable logic levels that you can configure as 1.2 V, 1.5 V,
1.8 V, 2.5 V, or 3.3 V. You can configure each channel as input or output.
