The Philippi P-Bus Relay Module CMR 232 S is a digital switching interface for Philippi's P-BUS onboard network, digitally switching, fusing, and monitoring up to 2 two-pole consumer circuits, each with a max of 30 A, via the PSM3 or PSL system monitors. It is suitable for high-power consumers on yachts, in campers, or off-road vehicles that require potential-free switching.
- Highest current rating of all CMR modules (30 A per channel) for high-power consumers such as compressor cool boxes or pumps
- Two-pole design enables potential-free switching of positive and negative leads
- Integrated emergency operation: In case of P-BUS system failure, each circuit remains manually operable via the fuse
- Optionally available with ATO fuse or circuit breaker, allowing flexible integration into existing systems
As part of the Philippi P-BUS system, the CMR 232 S seamlessly integrates into the digital onboard electrical system: Consumers are switched on and off using graphic symbols on the PSM3 or PSL system monitor, and the switching status as well as a defective fuse are displayed directly on the screen. Since the module switches two-pole, it is particularly suitable for applications where, for safety or installation reasons, both the positive and negative leads must be interrupted, such as with high-current consumers that need to be switched potential-free.
In the event of a system failure, the CMR 232 S is equipped with an integrated emergency operation: By relocating the fuse or circuit breaker, the respective output channel can be manually bridged, and the circuit can still be used without losing its protection. The Philippi P-BUS system is based on a CAN-Bus architecture and can be used for 12V and 24V onboard networks.

The CMR 232 S is part of the Philippi P-BUS system and is operated together with the PSM3 or PSL system monitors. It complements the other P-Bus relay modules (e.g., CMR 411, CMR 412) for applications with particularly high current loads.
What distinguishes the CMR 232 S from other CMR modules?
The CMR 232 S has the lowest number of channels in the P-Bus range with 2 channels, but the highest current rating of 30 A per channel in a two-pole design.
For which applications is the CMR 232 S suitable?
For two-pole consumer circuits with high current requirements up to 30 A per channel, for example, high-power consumers that need to be switched potential-free.
What happens in the event of a P-BUS system failure?
Each output channel can be bridged by relocating the fuse or circuit breaker, so the circuit remains manually operable even then.
