Switching actuator, 4-gang 16 A with manual actuation and current measurement for C-load, for KNX

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 separately from the bus or the 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.
Blocking function can be parametrised for each channel. As an alternative, forced setting function for each output.
Time functions (switch-on and switch-off delay, staircase light function – also with pre-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-hours 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.
The switching contacts of the switching actuator, 4-gang, C-load are especially designed for loads with a capacitive character, and therefore conditional, brief, high switch-on currents (see Technical Data).
The switching actuator has an integrated current detection.
A current measurement can be carried out for each channel.
Independent switching of the four outputs.
Current detection: Measurement of load current for each channel.
Threshold values for load monitoring (e.g. load failure notification).
