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