Information
RM 8 S KNX – 8-channel switch actuator with FIX1 module
Art. No. 4940220
Application
The Theben RM 8 S KNX is a compact and powerful 8-channel switch actuator for KNX installations, designed for switching various electrical loads such as incandescent, halogen, fluorescent, and LED lighting. Equipped with the FIX1 module, it is suitable for capacitive loads (C-load). Each output features LED status indication and manual operation is possible directly on the device – even without bus voltage. A reliable solution for high-performance KNX automation systems.
Main features
- 8-channel KNX switch actuator with FIX1 module for capacitive loads (C-load)
- LED status display per channel for quick diagnostics
- Manual control on the device, also possible without bus voltage
- Switching functions configurable via ETS: ON/OFF, impulse, ON/OFF delay
- Logic functions such as blocking, AND, OR, release
- Supports central commands: permanent ON/OFF, central switching, save/recall light scenes
- Potential-free outputs allow switching of different mains phases
- Suitable for SELV applications if all channels switch SELV circuits
