• The controller unit switches and dims electrical devices that have a 1-10 V interface

• Relays:
- Number: 4
• Contact: 1 x NO contact each, floating, flip-flop
• 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
- Coiled 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:

- Parallel-compensated: 2500 W / 200 µF
• Mercury vapour lamps:
- Uncompensated: 3680 W
- Parallel-compensated: 3680 W / 200 µF
• Ambient temperature: -5 to +45°C
• Connections:
- KNX: connection and junction terminal
- 1 – 10 V: screw terminals
- Load: screw terminals
• Connection cross-section: max. 4 mm²
• 5 device configurations can be selected. This leads to the assignment of 4 individually-controllable dimming channels to the switching outputs (e.g. 4 dimming channels are assigned to one switching relay to control an 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 for each channel following an ETS programming process
• Manual actuation of the outputs independently 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 operating hours counter
• Group feedback of all switching conditions possible
• Electronic ballasts generate very high current spikes. Use a switch-on current limiter or a separate load contact for greater loads.
• Connection and junction terminal supplied

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, 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 10 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 and NC contact operation
• Feedback of the switching state
• 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 into light scenes Up to 10 internal scenes per switching output are programmable
• Cyclical monitoring of incoming switching telegram is configurable
