Channel Diagnostics Over- or under-range by bit reporting

(1) Output ripple is the amount a fixed output varies with time, assuming a constant load and

temperature.

(2) Repeatability is the ability of the output module to reproduce output readings when the same

controller value is applied to it consecutively, under the same conditions and in the same direction.

(3) Rated working voltage is the maximum continuous voltage that can be applied at the output terminal,

including the output signal and the value that floats above ground potential (for example, 10V dc

output signal and 20V dc potential above ground).
