Abstract:
1. An electrofluidic control device comprising a plurality of electrically operable power modules arranged in a row direction and at least in part having at least one control valve, said power modules being jointly connected with an electrical concatenation strand extending in the row direction, wherein via said concatenation strand control signals employed for the control of the power modules are communicated and wherein via said concatenation strand the power modules are supplied with a first operating voltage, said first operating voltage being able to be supplied by way of a base connection provided on a connection module and connected with the concatenation strand, wherein for feeding of at least one further operating voltage there is in addition to the connection module at least one feed module having an electrical feed connection, said feed module being included or being able to be included in the course of the concatenation strand at a position spaced from the connection module, said electrical feed connection being externally accessible when said power modules are jointly connected with said electrical concatenation strand, the connection module and the at least one feed module being coordinated with galvanically separated operating voltage zones of the concatenation strand.
