5. THE VARIOUS I/O OPTIONS
The following chapter describes the various I/O options including the various I/O interfaces, I/O
boards and RTUs recognized by the DREAM system:
5.1 Interface for local I/O AC or DC
The local I/O interface may control 1 or 2 I/O boards of 16 outputs and 8 digital inputs. It
is meant for reading digital inputs and activating outputs, which are close enough to be directly
connected to the control unit.
