MCC 118: Maximum sampling rate

[GregorK]

Hello,

I want to stack 8 MCC118 DAQ hats on one Raspberry Pi to create a data logger with 64 input signals. If I read in all 64 channels consecutively in a for loop, what is the expected sampling rate (how often can I read in all 64 signals within a second)? I would implement it in python.

Hello @GregorK.

The MCC 118 DAQ HAT has a maximum aggregate sampling rate of 320 kS/s, for stacked boards.  If using 64 analog input channels, then each channel rate is effectively 5 kS/s.
