Information
RM 4 U KNX – 4-channel switching actuator with FIX1 module
Item No. 4940223
Application
The RM 4 U KNX from Theben is a versatile 4-channel switching actuator for KNX installations. The FIX1 module makes the device suitable for switching loads up to 16 A. With manual control and LED status indication per channel, it offers both reliability and ease of use. Ideal for controlling various lighting types including LEDs, fluorescent, incandescent, and halogen lamps in residential and commercial buildings.
Main features
- 4-channel KNX switching actuator with FIX1 module for loads up to 16 A
- Supports high inrush currents up to 800 A (200 µs)
- Manual control available per channel, even without bus voltage
- LED status indication for each channel
- Configurable functions via ETS: switching, pulse, on/off delay, staircase lighting
- Logic functions: blocking, AND, OR, release
- Supports central commands: permanent ON/OFF, central switching, scene storage/retrieval
- Potential-free outputs: suitable for switching different mains phases
- SELV application possible if all channels switch SELV only
