8 Electrical potential and data routing (Inline)

The Project+ software provides support when configuring an Inline station (see

Section “Appendix: Software support” on page 176).

8.1 Circuits and provision of supply voltages

There are several circuits within an Inline station. These are automatically created when

the terminals are properly installed. The voltages of the different circuits are supplied to

the connected terminals via potential jumpers.

An example of the circuits within an Inline station is given in Section “Example of a circuit

diagram” on page 85. The descriptions in the following sections refer to this example.

Please refer to the terminal-specific data sheet for the circuit to which the I/O cir-

cuit of a specific terminal is to be connected.

Carrying capacity of the

jumper contacts

Observe the maximum current carrying capacity of the jumper contacts on the side for

each circuit. The current carrying capacities for all potential jumpers are given in the fol-

lowing sections and are summarized in Section “Current and voltage distribution” on

page 91.

For the arrangement of the potential jumpers and information about current and voltage

distribution on the potential jumpers, please refer to Section “Electrical potential and

data routing” on page 87.

The connection of the supply voltages is described in Section “Connecting the power

supplies” on page 133.

For voltage connection, please observe the notes in the terminal-specific data

sheets.

8.1.1 Bus coupler supply

Please refer to the documentation for your bus coupler to determine the correct

supply voltage for the bus coupler.

The voltages for the logic circuit U

L

and the supply of the terminals for analog signals U

ANA

are always internally generated from the bus coupler supply.
