7.1
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 "Example of a circuit diagram"
on page 7-6. The descriptions in the following sections refer to this example.
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 following
sections and are summarized in "Current and voltage distribution" on page 7-12.
For the arrangement of the potential jumpers and information about current and voltage
distribution on the potential jumpers, please refer to "Electrical potential and data routing"
on page 7-8.
The connection of the supply voltages is described in "Connecting the power supplies" on
page 10-6.
7.1.1
The voltages for the logic circuit U
are always internally generated from the bus coupler supply.
The AX SALES software provides support when configuring an Inline station (see
"Software support" on page B-1).
Please refer to the terminal-specific data sheet for the circuit to which the I/O circuit of a
specific terminal is to be connected.
For voltage connection, please observe the notes in the terminal-specific data sheets.
Please refer to the documentation for your bus coupler to determine the correct supply
voltage for the bus coupler.
