Abstract (en)
[origin: EP0483642A1] The invention describes a circuit for electronic control systems with switch steps for acquisition and adaptation and switch means for provision of electric input signals. The object of the invention is to economise on components and space in the DC-isolation of the peripheral control side from the internal control plane, irrespective of the number of physical inputs. The object is achieved according to the invention by multiplexing all input information and by feeding the serial data stream via a DC-isolating element and a communication element to the microprocessor for further processing. The communication element contains a serial-parallel converter which converts the data stream into a bit word whose width corresponds to the quantity of input information. The control signals required for communication are used by a control logic located in an input module for synchronisation of the transmission cycle and are routed via DC-isolating elements. <IMAGE>
