Functions
Module supply
}
The module supply provides the module with voltage.
Signals at the output
}
“0” signal (0 V) at the output (O0+/O0-):
–
Output is high impedance
–
No current to the load
}
“1” signal (+24 V) at the output (O0+/O0-):
–
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 ter-
minals.
}
The periphery supply is used to supply the outputs.
Input
}
The input status is signalled to the head module via the module bus.
}
The input has an input filter.
