The Basic I/O 1
ANALOG OUTPUTS:
Analog output modules are 100% isolated. These 
Analog output instruction types are:
Level Value  | Can set output levels, as a fraction of the module’s full scale  | 
  | range, and are specified with 12 bit (1 part in 4096) resolution.  | 
Waveforms  | Can provide square, triangle, sawtooth or ramp waveforms,  | 
  | Maximum and Minimum amplitudes, as a fraction of the output  | 
  | module’s full scale range, are specified with 12 bit (1 part in  | 
  | 4096) resolution. Waveform periods are specified from 0.1 to  | 
  | 6,553 seconds (about 109 minutes).  |
