Chapter 1. INTRODUCION
Digital/analog conversion module allows digital value of the CPU to be converted into an analog value
and to be output externally. Digital input value of 0 leads to analog output value of 0V and 4000 leads
to 10V. Digital input value of 1 is equal to 2.5mV.

Digital/analog conversion module allows digital value of the CPU to be converted into an analog value
and to be output externally. Digital input value of 0 leads to analog output value of -10V and 4000 leads
to10V. Digital input value of 1 is equal to 5mV.
