Issue Details

I am using a cDAQ (such as the cDAQ-9178) loaded with a NI-9234 module for my application where I am acquiring low frequency signals. 

I need to know the minimum sample rate of the NI-9234 C Series.

Solution

The minimum sample rate for the NI-9234 depends on the master timebase.

Using the default master timebase, the minimum sample rate is 1.652 kS/s.

Using a custom master timebase,you can achieve rates below this.
The "Data Rates" section of the NI-9234 Datasheet  explains how the minimum sampling rate is determined for any given timebase.
