Control apparatus with load monitoring

A modular control apparatus having a head module, at least one power supply module and at least one peripheral module, which are arranged next to one another on the head module, and having at least one bus structure,

• wherein the at least one power supply module and the at least one peripheral module each have a base module part, an electronic module part and a connection module part, the power supply module being configured to supply the at least one peripheral module with an external peripheral current,
• wherein the connection module part of the at least one power supply module has a supply connection for receiving the external peripheral current,
• wherein the connection module part of the at least one peripheral module provides an output connectable to an actuator for outputting the peripheral current received from the power supply module,
• wherein the base module parts arranged next to one another form the bus structure that electrically couples the head module, the at least one power supply module and the at least one peripheral module to one another so that the external peripheral current is transferred via the bus structure from the at least one power supply module to the at least one peripheral module, and
• wherein the power supply module additionally comprises:
• an electrical line, having a defined cross section, that runs from the connection module part through the electronic module part to the base module part and connects the at least one supply connection of the power supply module to the bus structure,
• and an overload identification unit that is arranged proximate to the electrical line and determines a parameter of the electrical line and produces a warning signal if the parameter exceeds a threshold value.
