Abstract
A circuit configuration for controlling a major number of consumers (5) such as the electromagnetically operable multi-directional valves of an anti-lock control system (MWV1-MWVn) comprises a control unit (2, 3) whose output signals can be fed to the consumers (5) via amplifier stages (4). The individual amplifier stages (4; VS1-VSn) are designed as so-called 'intelligent power drivers' and essentially consist of a power amplifier (18) with integrated electronic controls and monitors. The control unit (2, 3) and the amplifier stages (4; VS1-VSn) are interconnected to form a closed loop or chain. Data transfer is performed from a synchronous serial interface of the control unit (2, 3), via the individual amplifier stages (4; VS1-VSn) and back to a serial entry of the control unit (2, 3).
