Digital input and output terminals and relay terminals are available for the low voltage area.
These terminals are available in different sizes. This enables you to set up the station in a
modular way so that it meets your application requirements.
Figure 4-8
Overload protection of the system is provided centrally by a fuse in the power terminal or by
an external fuse provided by the operator. The rating of the preconnected fuse must be such
that the maximum load current is not exceeded. For the maximum permissible load current
of an I/O terminal, please refer to the terminal-specific data sheet.
The maximum current carrying capacity of the jumper contacts on the side is specified in
"Current and voltage distribution" on page 7-12.
Connection to functional earth ground (24 V DC area) or protective ground (120 V AC or
230 V AC area) is established via the corresponding potential jumpers when the terminal is
snapped onto the previous terminal.
