Functions
Module supply
}
The module supply provides the module with voltage.
Signals at the output
}
"0" signal (0 V) at the output:
– Output is high impedance
– No current to the load
}
"1" signal (+24 V) at the output:
– Output is low impedance
– Current is supplied to the load
Periphery supply
}
The module routes the periphery supply from the module bus to the base module termin-
als.
}
The periphery supply is used to supply the outputs.
Outputs
}
The head module sets the output status via the module bus.
