Module features
4.1.1
Supply voltage
The product provides the module supply and periphery supply for the modules on the mod
ule bus:
}
Module supply
Supply voltage for subsequent module (righthand side)
}
Periphery supply
Supply voltage for sensors, actuators and test pulses
}
Crail
Infeed of the permitted additional supplies for the Crail; a detailed description of how to
use the Crail can be found in the system description.
When the supply voltage is fed in separately, the module supply and periphery supply are
galvanicaly isolated. If galvanic isolation is not required, a common power supply may be
used for the periphery supply and module supply.
The module enables
}
The module supply and periphery supply to be refreshed:
The relevant base module interrupts the connection to the incoming (lefthand) module
supply, periphery supply and Crail on the module bus. The 0 V supply on the module
supply is connected to the left and right.
}
Supply groups to be formed
The relevant base module interrupts the connection to the incoming (lefthand) peri
phery supply and Crail on the module bus. Each supply group requires its own supply
module.
4.1.1.1
Current load capacity
Ensure you comply with the current load capacity of the module and periphery supply (see
"Technical Details"). If the current load is higher, an additional supply voltage module is re
quired to refresh the module supply and periphery supply.
}
Module supply
The current load is the total current consumption of all the electronic and compact mod
ules.
The module supply does not automatically switch off if values exceed or drop below
their limits. However, the "5 V" LED will light and a message will be entered in the dia
gnostic log.
}
Periphery supply
The current load is the total current consumption of the sensors, actuators and test
pulses supplied via the input/output modules.
The periphery supply does not automatically switch off if values exceed or drop below
their limits. However, the "24 V" LED will light and a message will be entered in the dia
gnostic log.
