摘要： A circuit arrangement for controlling a plurality of loads of an electrical appliance has a main control module, arranged in a first voltage range and configured to generate control data for controlling a plurality of loads, which are arranged in a second voltage range. A galvanic isolation unit transfers the control data via a galvanically isolated connection from the first voltage range to the second voltage range. At least one auxiliary control module has a plurality of control outputs for the loads and an LED driver for operating a corresponding plurality of LED arrangements via the of control outputs, and/or a general-purpose input/output expansion circuit with programmable control outputs. Based on the control data, the auxiliary control module identifies a first control output for controlling the first load and causes the first load to be controlled via the first control output.
