Output Module Block Diagram
The output module uses a digital-to-analog (D/A) converter to read the digital
output data from the controller and convert it to an analog output signal.
Figure 1.7 1769-OF2 Block Diagram
Figure 1.8 1769-OF8C and -OF8V Block Diagram
The following diagram shows only one of eight outputs. For each analog
output, only one of the sections shown in broken-line boxes is implemented.
The 1769-OF8C module uses only the Current Out section while the
1769-OF8V module uses only the Voltage Out section.
