4-Station Pump Relay Box for Seamless DC System Integration by MBC Marine!
The 4-Station Pump Relay Box is engineered to control a common seawater pump shared among up to four DC air conditioning units, ensuring efficient and coordinated operation.
Our Pump Relay (PRP) board enables smooth, automatic switching of a shared seawater pump between multiple DC A/C units.
Each unit is equipped with independent, fully isolated pump trigger inputs compatible with 12V or 24V DC signals, guaranteeing safe and flexible integration.
The pump power input and output are also isolated and suitable for 12V or 24V DC systems. Housed in a plastic enclosure, the relay box allows clean, organized wiring for all control inputs and pump connections—offering a dependable, space-saving solution for modern marine DC air conditioning setups.
