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 module routes the periphery supply from the module bus to the base module termi-
nals.
}
The periphery supply is used to supply the outputs.
Outputs
}
The head module sets the output status via the module bus.
The module provides advanced diagnostic data, which is also available in a status byte in
the ST-PII (not in system environment B):
}
Output overload/short circuit
}
Excess module temperature
Permitted capacitive load based on output current
