Mastervolt 79007100 Relay Excl

Mastervolt Relay Excl. / Relay Interface Module (79007100)

The Mastervolt 79007100 is a specialized auxiliary Relay Switching Module / Relay Board designed for integration into Mastervolt marine, mobile, and industrial power conversion systems. Engineered as an essential control component for systems like Mastervolt Mass, ChargeMaster, and AC Master installations, it facilitates remote power switching, automatic transfer logic, fault alarms, and load shedding routines.

Built on a heavy-duty fiberglass printed circuit board (PCB) with high-dielectric insulation, the 79007100 module isolates sensitive low-voltage DC control circuits from high-power AC/DC loads. Its high-grade contacts ensure low contact resistance and reliable latching operation even under heavy inductive starting currents, continuous thermal stress, and high vibration marine environments.

Key Features

• High System Integration: Designed to interface seamlessly with Mastervolt chargers, inverters, and transfer systems.

• Galvanic Isolation: Separates control signal logic from primary switching contacts to prevent voltage spikes and ground loops.

• Vibration & Moisture Resistant: Conformal coated board construction resists moisture ingress, salt mist, and mechanical shock aboard vessels.

• Heavy-Duty Relay Contacts: High-amp rating contacts designed to handle inductive motor and transformer switching loads cleanly.

• Low Power Coil Consumption: Optimized coil drive circuit minimizes parasitic battery draw during extended standby periods.
