KNX Ctrl.unit 1 - 10 V 4-g man.act. [222400] KNX control unit 1 – 10 V, 4-gang with manual actuation Other electronics DRA plus Features: - The controller unit switches and dims electrical devices that have a 1-10 V interface. - Five device configurations can be selected. This leads to the assignment of four individually-controllable dimming channels to the switching outputs (e.g. four dimming channels are assigned to one switching relay to control a RGBW light). - Relay outputs that are not associated with a dimming channel can be used as freely-acting switching actuator channel. - Reactions in case of bus voltage failure and restoration can be set following an ETS programming process. - Manual actution of outputs independent of the bus with mechanical switching position indication. - Delay for actively transmitted feedback messages following bus voltage recovery. - Logical linking function configurable per channel. - Up to three central switching functions for the joint control of all dimming and switching channels. - Switch-on times of the relay outputs can be recorded and evaluated by the elapsedoperating time meter. - Group feedback of all switching conditions possible. Dimming channels - Four individually-controllable dimming channels. - Feedback on switching condition and brightness value. - Dimmable brightness range can be set. - Dimming behaviour and dimming characteristics can be parameterised. - Soft switch-on and soft switch-off function - Block function or forced setting function can be parameterised. - Time functions (switch-on delay, switch-off delay, staircase light function). With the staircase light function, the reaction at the end of the switch-on time can be configured. - Inclusion of a dimming channel in up to ten scenes is possible. - The burning-in function allows for the start-up of new fluorescent lamps prescribed by lighting manufacturers. Switching actuator operation (optional) - Independent switching of switch outputs A2 to A4. - NO contact or NC contact operation. - Feedback from the switching condition. - Block function or forced setting function can be parameterised. - Time functions (switch-on, switch-off delay, staircase light function - also with advance warning function). - Can be integrated in the light scenes. Up to ten internal scenes per switching output are programmable. - Cyclical monitoring of incoming switching telegram is configurable.
