Patent ID: 7881828

Claim:
A bus module for connecting electrically triggerable fluidic valves to a data bus, comprising: an electrical circuit configuration, which evaluates address data and user data from data telegrams transmitted on the data bus and which triggers the fluidic valve determined by the address data in accordance with the user data of the data telegram, wherein: following the reception of user data in the form of a switch-on command for one of the fluidic valves connected to the bus module, the electronic circuit configuration constantly supplies a supply voltage to the fluidic valve determined by the address data during a gate-controlled rise time of specifiable duration, following the expiration of the gate-controlled rise time, the electronic circuit configuration supplies to the fluidic valve the supply voltage in pulse-width modulated form having a specifiable pulse control factor, and following the reception of user data in the form of a switch-off command, the electronic circuit configuration no longer supplies a supply voltage to the fluidic valve for the previously switched-on fluidic valve.
