2 Overview
Module structure:
A module consists of
}An electronic module
}A terminal block with cage clamp terminals and
}A backplane
The electronic modules are plugged into the backplane and determine the function. The
backplane is used for communication between the head module and the electronic modules
and forms the carrier unit for the electronic modules. The terminal block is plugged into the
electronic modules and is used to connect the field wiring.
Details of the terminal blocks that can be used are available under "Intended Use".

4.2 Supply
}The module supply provides the module with voltage.
4.3 Integrated protection mechanisms
}The module has temperature monitoring.
The module provides the following diagnostic data:
}Start-up error
}Configuration error
}ST communication error
}Temperature error: too warm
}Temperature error: too hot
4.4 Outputs
The module has 4 relay outputs with a changeover contact.
Outputs
}The head module sets the output status via the module bus.
If the module does not receive a process image of outputs from the head module, then sub-
stitute values are used for the process data. The value that is to be used as the substitute
value can be configured.
Substitute values may be:
}Output switched off (default value)
}Output switched on
