Information
RM 4 I KNX – 4-channel C-load switching actuator
Item no. 4940210
Application
The RM 4 I KNX (item no. 4940210) by Theben is a powerful 4-channel switching actuator for KNX systems, suitable for high electrical loads such as LEDs, fluorescent lamps, incandescent and halogen lighting. Equipped with a FIX1 module, this actuator is optimized for capacitive loads (C-load) up to 16 A and features current detection per channel. The switching outputs can be operated manually—even without bus voltage—and offer LED status indication for each channel.
Main functions
- 4-channel switching actuator for capacitive loads (C-load) up to 16 A
- FIX1 module: suitable for high inrush currents (max. 1500 A / 200 µs)
- Current detection per channel with measurement accuracy from 150 mA
- Manual operation directly on the device, even without KNX bus voltage
- LED status indication for each channel
- Flexible parameterisation via ETS: switching, impulse function, delays, staircase lighting with pre-warning
- Logic functions: blocking, releasing, AND/OR operations
- Supports central functions: on/off, scene saving and recall
- Supports switching of different phases and SELV circuits (if all channels are configured for SELV)

Important notes
- The RM 4 I KNX is designed for switching high loads such as LEDs with high inrush currents – use only with suitable wiring and installation standards.
- ETS software (version 5 or higher) is required for full configuration.
- Switching of different phases is possible thanks to potential-free outputs.
- Manual control remains available even without KNX bus voltage.
- For accurate current measurement, each channel must be loaded with at least 150 mA.
