Control unit 1 – 10 V, 4-gang with manual actuation for KNX

• The control unit switches and dims electrical devices that feature 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 actuation of the outputs independently of the bus with mechanical switching position indicator.
• 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 elapsed-hours 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 commissioning 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.

• Electronic ballasts generate very high current spikes. For this reason, use a switch-on current limiter or a separate load contact for with greater loads.

• Connection and junction terminal for KNX included with delivery.
