Function description
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 Periphery Supply is not provided via the module bus, but it has to be fed via the
connectors.
}
The periphery supply is used to supply the outputs.
Outputs
}
The head module sets the output status via the module bus.
