The Philippi P-Bus relay module CMR 412 S is a digital switching interface for the Philippi P-BUS onboard network, which digitally switches and fuses up to 4 two-pole consumer circuits, each with a maximum of 10 A, and controls them via the PSM3 or PSL system monitors. In addition, dimmable LED lights can be controlled via 4 PWM control channels – suitable for yachts, campers and off-road vehicles with potential-free switchable loads.
- 4 two-pole switching channels for potential-free switching of positive and negative lines
- 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 available with ATO fuse or with circuit breaker
The CMR 412 S is the two-pole version of the CMR 411 S in the Philippi P-BUS program: With the same number of channels (4), the same current load (10 A per channel) and the same PWM dimmer function, the CMR 412 S switches both the positive and the negative line. This is advantageous wherever consumers are to be switched potential-free for safety or installation reasons. Consumers can be operated via graphic symbols on the PSM3 or PSL system monitors, and the switching status and a defective fuse are displayed directly on the screen.
With the CMR 412 S, the integrated emergency operation also ensures that in the event of a P-BUS system failure, each output channel can be manually bypassed by repositioning the fuse or circuit breaker, without losing protection. The Philippi P-BUS system is based on CAN-Bus technology and is designed for 12V and 24V onboard networks.

The CMR 412 S is part of the Philippi P-BUS system and is controlled via the PSM3 or PSL system monitors. For single-pole consumers, the identical CMR 411 S is available; for higher current loads in a two-pole version, the CMR 232 S is available.
What is the difference between the CMR 412 S and the CMR 411 S?
The CMR 412 S switches two-pole consumer circuits, while the CMR 411 S switches single-pole circuits – with the same number of channels (4), current load (10 A) and PWM dimmer function.
What is the two-pole version suitable for?
For consumers where both the positive and negative lines are to be switched, for example for potential-free switching.
Can the CMR 412 S dim LED lights?
Yes, dimmable LED lights or LED power drivers can be dimmed from the monitor via the 4 PWM control channels.
