Electronic circuit arrangement for control purposes

The electronic circuit arrangement ( 30 ) for controlling a process device ( 40 ) comprises a process interface circuitry ( 1 ) and a processing circuitry ( 2 ), wherein the process interface circuitry ( 1 ) is designed for receiving process signals from the process device ( 40 ) and converting the process signals into converted signals and/or digital data, which converted signals and/or digital so data are transmitted to the processing circuitry ( 2 ), and wherein the processing circuitry ( 2 ) is designed for processing the converted signals and/or digital data and for outputting processed signals and/or digital data, which processed signals and/or digital data are transmitted to the process interface circuitry ( 1 ), and wherein the process interface circuitry ( 1 ) is designed for converting the processed signals and/or digital data into control signals, which control signals are transmitted to the process device ( 40 ). The process interface circuitry comprises one or more first printed circuit board assemblies ( 10 ), and the processing circuitry comprises one or more second printed circuit board assemblies ( 20 ), which second printed circuit board assemblies ( 20 ) are different from the first printed circuit board assemblies ( 10 ), and wherein each second printed circuit board assembly ( 20 ) is electrically connected to at least one of the first printed circuit board assemblies. The circuit arrangement ( 30 ) may find applications in high or medium voltage devices, in drives and in power converters.
