Configuring Analog Input and Output Parameters
Analog Outputs
The RGU has two 12-bit, digital-to-analog convertors (DAC) rated to
provide analog outputs in the range of +/- 10V DC. The two DACs
are labeled DAC1 and DAC2.
Each DAC is programmed using 4 parameters that identify the value
to be sent to the analog output and specify how that value needs to be
scaled prior to digital-to-analog (D/A) conversion. Refer to Figure
11.1 for a block diagram. These parameters are as follows:
The following DAC parameter allows you to view the scaled value
prior to D/A conversion:
The analog output is accessible via terminal block 1 (TB1) on the
main control board as follows:
