The NI PXIe-7867R 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 a fixed logic level of 3.3 V. You can configure each channel

as input or output.
