Available I/O functionality:

Analog Input Functions

Input value Determines signal levels, with 12 bits resolution

Offsets Input values can be software offset, with 12 bits resolution,

over the module’s specified range.

Gain/ Slope The amplitude of input values can be software multiplied by

factors ranging from 0.25 to 4.0.

Range Limits The occurrence of input values falling out of user defined upper

or lower limits can be flagged.

Minimums The minimum level of input values can be captured.

Maximums The maximum level of input values can be captured.

Averages Can calculate average input amplitude for 1-65,535 samples.

Temperature Can linearize in, °C, inputs from thermocouples and RTDs.

Will also return temperature probe data.

Analog outputs

Level Value Can set output levels, as a function of the module’s full scale

range, and are specified with 12 bits resolution.

Waveforms can provide square, triangular, sawtooth, or ramp waveforms.

Maximum and minimum amplitudes, as a fraction of the output

module’s full scale range, are specified with 12 bits

resolution. Waveform periods are specified 0.1 to 6,553 Sec

(109 Min). All waveforms are made up of at least ten

segments.
