If you set the sample rate (the main channel sample rate setting) of the DL850E/DL850VE to a rate
that exceeds the sub channel data update rate, all data within the sub channel data update interval
will be the same.

The sample rate (data update rate) of the 4-CH 1MS/s,
16-bit isolation module is always one-half that of the two-
channel module regardless of the number of sub channels
to be used.
