The P-Bus relay module CMR 811 S is a digital switching interface for the Philippi P-Bus system, digitally switching up to 8 single-pole consumer circuits, each with a maximum of 10 A, and is controlled and monitored via the PSM3 or PSL system monitors. It is suitable for yachts, motorhomes, and vehicles with many smaller consumers that need to be centrally controlled.
- Switches up to 8 circuits via a single module, instead of wiring a separate relay for each consumer
- 4 integrated PWM dimmer control channels for dimmable LED lights, e.g., Prebit Secondary lights
- Main/Secondary function: one switching command controls multiple outputs simultaneously
- Manual emergency operation: each output channel can be bypassed by repositioning the fuse or circuit breaker
In the onboard electrical system, the Philippi P-Bus relay module CMR 811 S takes over the digital switching and monitoring of numerous consumer circuits, without the need for a separate mechanical switch on the switch panel for each circuit. Via the 4 PWM control channels, dimmable LED lights can also be controlled directly from the PSM or PSL system monitor. The module is available in two versions: with ATO fuse or with circuit breaker.
| Feature | Value |
|---|---|
| Switching Channels | 8 (1-pole) |
| Current load per channel | 10 A |
| Inputs | 8 |
| Additional Function | 4 PWM dimmer control channels for dimmable LED lights |
| Dimensions | W 140 x L 180 x H 50 mm |
| Fuse version | ATO fuse, order no. 0 7100 0811 (SKU 071000811) |
| Circuit breaker version | Circuit breaker, order no. 0 7100 1811 (SKU 071001811) |
The CMR 811 S is part of the Philippi P-Bus system and is operated with the PSM3 or PSL system monitors. It complements other P-Bus relay modules such as the CMR 431 (4 channels, 30 A, without PWM) or the CMR 411 (4 channels, 10 A, with PWM dimmer) for a precisely tailored distribution of consumers on board.
How many circuits can the CMR 811 switch?
Up to 8 single-pole consumer circuits, each with a max. of 10 A.
What distinguishes the CMR 811 from the CMR 411?
The CMR 811 offers 8 instead of 4 switching channels and 8 instead of 4 inputs, with the same current load of 10 A per channel and identical PWM dimmer function.
Is emergency operation possible?
Yes, each output channel can be bypassed by repositioning the fuse or circuit breaker, so that the circuit remains manually operable even in the event of a system failure.
