- Switching current 230 V AC3: 10 A
- Switching current 400 V AC1: 10 A
- Switching current 400 V AC3: 6 A
• The control unit switches and dims electrical loads that have a 1-10 V interface

• Relay:

- Contact: 1 x NO contact each, floating, bistable
• Control outputs:
- Control current per output: max. 100 mA
- Cable length: max. 500 m with 0.5 mm²
- Fluorescent lamps: 16 AX
• Lamp loads:
- Incandescent lamps: 3680 W
- HV halogen: 3680 W
- Wound transformer: 2000 VA
- Tronic transformer: 2500 W
• Fluorescent lamps T5/T8:
- Uncompensated: 3680 W
- Parallel-compensated: 2500 W / 200 µF
- Duo circuit: 3680 W / 200 µF
• Compact fluorescent lamps:

- Uncompensated: 3680 W
- Parallel compensated: 3680 W / 200 µF
• Ambient temperature: -5 to +45°C
• Connections:
- KNX: Connection and branch terminal
- 1 - 10 V: Screw terminals
- Load: Screw terminals
• Connection cross-section: max. 4 mm²
• 5 device configurations can be selected. This is used to assign the 4 individually controllable dimming channels to the switching outputs (e.g. 4 dimming channels are assigned to a Switching relay to control an RGBW light)
• Relay outputs that are not assigned to a dimming channel can be used as freely acting switching actuator channels
• Reactions on bus voltage failure and recovery and after an ETS programming operation can be set
• Manual actuation of the outputs independently of the bus with mechanical switching position indicator
• Delay for actively transmitting feedback signals after bus voltage recovery
• Logical linking function configurable for each Ducts
• Up to three central switching functions for common control of all Dimmers and switching channels
• Switch-on times of the relay outputs can be recorded and evaluated by operating hours counters
• Collective feedback of all switching states possible
• Electronic ballasts generate very high current peaks. Therefore, use an inrush current limiter or a separate load contactor for larger loads
• Connection and branch terminal included in the scope of delivery

Dimming channels:
• Four individually controllable dimming channels
• Feedback of switching status and brightness value
• Setting of the dimmable brightness range possible
• Dimming behaviour and dimming characteristics can be parameterised
• Soft switch-on and soft Off-switch function
• Disable function or forced position function can be parameterised
• Time functions (switch-on, switch-off delay, staircase lighting function). With the staircase lighting function, the reaction at the end of the switch-on time can be parameterised
• Inclusion of a dimming channel in up to 10 scenes possible
• Burn-in function enables the commissioning of new Fluorescent lamps as prescribed by the light source manufacturer

Switch actuator operation (optional):
• Independent switching of Switches A2 to A4
• Normally open or normally closed operation
• Feedback of the switching status
• Disabling function or forced position function can be parameterised
• Time functions (switch-on, switch-off delay, staircase lighting function with pre-warning function)
• Inclusion in light scenes possible. Up to 10 internal scenes can be parameterised for each switching output
• Cyclical monitoring of the incoming switching telegram can be configured
