Abstract (en)

[origin: US7881828B2] A bus module for connecting electrically triggerable fluidic valves to a data bus. The bus module has an electrical circuit configuration, which evaluates address data and user data from data telegrams transmitted on the data bus and which triggers a fluidic valve determined by the address data in accordance with the user data of the data telegram. In order to keep the current load on the bus module low particularly when triggering hydraulic valves, the electronic circuit configuration, 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, first 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 the fluidic valve with the supply voltage in a pulse width modulated form having a specifiable pulse control factor. Only when the bus module has received user data in the form of a switch-off command for the previously switched-on fluidic valve, does the electronic circuit configuration no longer supply a supply voltage to the fluidic valve.
