KNX DRA swit.act. 4-g 16 A man.act. + C-load [104500] Switching actuator, 4-gang 16 A with manual actuation and current measurement for C-loads, for KNX Gira KNX system DRA plus 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. - 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. signalling of load failure).
