Device description

Please note, that some I/O terminals may have no or just single power contacts (depending on the function of the terminal). Therefore the daisy chaining of power supplies from module to module may be interrupted. If it is necessary to supply subsequent terminals (more right positioned), an additional power supply terminal is necessary. With some terminals it is basically not possible to connect them together because the grooves for the blade contacts are closed at the top.

With the placement of an additional power terminal, the field supply via the power contacts is always interrupted. This means that a new power supply is provided from this point on, which can also include a potential change. This option ensures a high flexibility of the overall system.

Please note, that some terminals additionally require an own power supply (mostly 24 V DC). These are mainly modules of the type “complex terminals”, see chapter Terminal types.

Please refer to the manufacturer’s original manual(s) for more information.
