DRA switching actuators with integrated bus coupler. For switching independently controllable groups of loads. With manual switch for switching over the relay (On/Off) parallel or without KNX operation. Multi-phase connection. No additional power supply required.
Features
- Manual actuation of the relay independent of the bus or switching position indication.
 
- NO contact or NC contact operation.
 
- Central switching function.
 
- Group feedback for reduction of bus load.
 
- Active or passive (object can be read out) cyclical feedback function.
 
- Feedback can be delayed until after the recovery of bus voltage.
 
- Logical linking function for each output.
 
- Block function can be parameterised for each channel. As an alternative, forced setting function for each output.
 
- Time functions (switch-on/off delay, staircase light function – also with advance warning function).
 
- Integration in light scenes is possible, eight internal scenes at the most can be parameterised per channel.
 
- Memory function for light scenes.
 
- Elapsed operating time meter as forward/backward counter with limit function (limit can be changed via bus) can be activated for each output.
 
- Input monitoring for cyclical updating with safety setting.
 
- Reactions in case of bus voltage failure and restoration can be set for each channel following an ETS programming process.
 
- Independent switching of the two outputs.
