Module features
4.2.1
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 (right-hand side)
}
Periphery supply
Supply voltage for sensors, actuators and test pulses
}
C-rail
Infeed of the permitted additional supplies for the C-rail; a detailed description of how to
use the C-rail 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 (left-hand) module
supply, periphery supply and C-rail 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 (left-hand) peri-
phery supply and C-rail on the module bus. Each supply group requires its own supply
module.
