Abstract: A functional module for a switch device control is disclosed. In at least one embodiment, the functional module includes—a communication unit having a communication interface for communicating with at least one further functional module and/or at least one coupling module,—a control unit connected to the communication unit and designed to receive signals transmitted from the at least one further functional module and/or the at least one coupling module to the communication unit and to transmit switch commands via the communication unit to the at least one further functional module and/or the at least one coupling module,—a first control current interface for the electric connection to a first switch device or an external energy supply unit, and—a second control current interface for supplying control current to the at least one further functional module and/or the at least one coupling module.

Abstract: A monitoring unit is disclosed for monitoring the load of an electric motor. In at least one embodiment, the monitoring unit provides for the motor load to be monitored over the entire torque range. For this purpose, the monitoring unit uses linearizing matching of the indication variable. First, the monitoring unit is provided for detecting a motor current and a phase angle between the supply voltage and the motor current in the operating state of the motor. Furthermore, it includes at least one device for forming an indication variable from the motor current and the phase angle as a measure for monitoring the electric load of the motor.
