Switching actuator for controlling the energy supply to electric consumers

1. A switching actuator for controlling the energy supply to at least one electrical consumer with an energy supply input, an energy supply output, a signal line input, a signal line output and an evaluation unit, the evaluation unit being adapted to activate or deactivate the energy supply output on the basis of signals input via the signal line input;

wherein, when the switching actuator receives a signal above a dimming setting of 0, the switching actuator transmits a “broadcast OFF” to all of each of the at least one electrical consumer not intended to be activated directly after activation of the energy supply.

2. The switching actuator as claimed in claim 1 , wherein the signal line input and a signal line output have bidirectional connections.

3. The switching actuator as claimed in claim 2 , wherein the signal line input and the signal line output each have two-wire lines corresponding to the DALI standard.

4. The switching actuator as claimed in claim 1 , wherein the evaluation unit for activating or deactivating the energy supply output has a connection to a switching element, it being possible for a connection to be produced between the energy supply input and the energy supply output via the switching element.

5. The switching actuator as claimed in claim 4 , wherein the switching element is a relay.

6. The switching actuator as claimed in claim 1 , wherein the evaluation unit is adapted to check addresses and/or group assignment of electrical consumers or to record said addresses and/or group assignment in a commissioning phase.

7. The switching actuator as claimed in claim 6 , wherein the evaluation unit is adapted to transmit signals to predetermined addresses and/or groups via the signal line output.

8. The switching actuator as claimed in claim 1 , wherein the evaluation unit comprises a monitoring unit and a status memory.

9. The switching actuator as claimed in claim 1 , wherein the evaluation unit has inner logic with which the energy supply output can be activated or deactivated based on signals detected at the signal line input.

10. A control unit, comprising a switching actuator as claimed in claim 1 .

11. A system for controlling the energy supply to electrical consumers comprising a control unit and at least one electrical consumer, and a switching actuator as claimed in claim 1 is arranged between the control unit and the electrical consumer.

12. The system as claimed in claim 10 , wherein at least one electrical consumer is electronic control gear, and the evaluation unit is adapted to check the dimming setting of electronic control gear.

13. A switching actuator for controlling the energy supply to at least one electrical consumer with an energy supply input, an energy supply output, a signal line input, a signal line output and an evaluation unit, the evaluation unit being adapted to activate or deactivate the energy supply output on the basis of signals input via the signal line input;

wherein, when the switching actuator receives a DALI signal which requires a dimming setting of >0 for at least one downstream group of electronic control gear, a switching element of the switching actuator activates the energy supply, repeats the received DALI signal and transmits corresponding “OFF” signals to prevent a luminous device of unaffected electronic control gear from being switched on in an undesired manner.
