The Philippi P-Bus relay module CMR 411 S is a digital switching interface for Philippi's P-BUS onboard network, digitally switching and protecting up to 4 single-pole load circuits, each with a maximum of 10 A, and controlling them via the PSM3 or PSL system monitors. Additionally, dimmable LED lights can be controlled via 4 PWM control channels – ideal for yachts, campers, and off-road vehicles with digital onboard electronics.
- 4 independent switching channels for lighting, pumps, or other small loads, centrally operable via the monitor
- Dimming function via 4 PWM control channels for dimmable LED lights (e.g., Prebit Secondary) directly from the system monitor
- Integrated emergency operation: circuit remains manually operable via the fuse in case of system failure
- Optionally with ATO fuse or with circuit breaker, thus suitable for various system concepts
In the Philippi P-BUS system, the CMR 411 S handles the digital switching and monitoring of several single-pole circuits simultaneously. Connected loads can be switched on and off via graphic symbols using the PSM3 or PSL system monitors; the switching status and a defective fuse are displayed directly on the screen. Particularly practical for interior lighting: The brightness of dimmable LED lights or LED power drivers with a suitable control input, such as Prebit lights in the Secondary version, can be conveniently adjusted from the monitor using the four PWM dimmer channels.
Should the P-BUS system fail, each output channel of the CMR 411 S remains usable: By repositioning the fuse or circuit breaker, the circuit is manually bypassed, while the protection remains. The Philippi P-BUS system is CAN-Bus based and can be used in both 12-V and 24-V onboard networks.

The CMR 411 S is part of the Philippi P-BUS system and is controlled via the PSM3 or PSL system monitors. For two-pole loads, the structurally identical CMR 412 S is available; for higher current loads, the CMR 232 S or CMR 431.
What does the CMR 411 S do?
It switches and monitors up to 4 single-pole load circuits, each with a maximum of 10 A, digitally via the PSM3 or PSL system monitors.
Can the CMR 411 S dim LED lights?
Yes, dimmable LED lights or LED power drivers with appropriate control input, e.g., Prebit Secondary, can be dimmed from the monitor via the 4 PWM control channels.
What happens in case of a system failure?
Each output channel can be bypassed by repositioning the fuse or circuit breaker, so that the circuit remains manually operable while the protection is maintained.
