Information
RM 8 I KNX – 8-channel C-load switch actuator
Art. No. 4940215
Application
The RM 8 I KNX from Theben is a powerful 8-channel switch actuator for KNX installations, designed for switching high electrical loads such as LEDs, fluorescent lamps, incandescent and halogen lamps. Thanks to the FIX2 module, the device is optimally suited for capacitive loads (C-load) up to 16 A per channel and delivers reliable performance with high inrush currents up to 1500 A (200 µs). The switching outputs feature current detection per channel and can be manually operated even without KNX bus voltage. LEDs display the switching status of each channel individually.
Main functions
- 8-channel switch actuator for capacitive loads (C-load) up to 16 A
- FIX2 module: suitable for high inrush currents (max. 1500 A / 200 µs)
- Current detection per channel with accuracy starting from 150 mA
- Manual operation per channel, even without bus voltage
- LED status indication for each channel's switching state
- Configurable via ETS: switching, impulse function, on/off delay, staircase lighting with pre-warning
- Logic functions such as blocking, AND, OR, release
- Support for central commands: always ON/OFF, central switching, save and recall light scenes
- Suitable for switching different phases
- SELV operation possible if all channels switch only SELV

Important notes
- The RM 8 I KNX is optimized for switching high loads with high inrush currents – use only with suitable wiring and in accordance with current installation standards.
- Configuration via ETS software (version 5 or higher) is required for full functionality.
- Thanks to potential-free outputs, switching of different mains phases is possible.
- Manual operation is always available, even without active KNX bus voltage.
- For accurate current measurement, each channel must have a load of at least 150 mA.
