For larger breakers and more circuits, the MPower(R) CLMD16 is a 16-Channel DC Load Controller Module. Four of the 16 breakers handle a maximum of 25 amps and twelve breakers handle a maximum of 12 amps with a total current capacity of 125 Amps. Additionally, circuits can be paralleled.

The CLMD16 also supports two H-Bridge reversing polarity circuits that can be used for loads such as engine hatches, passerelles, trim tabs, etc. The CLMD16 has 8 inputs for hard-wired switches that can be used to switch breaker states, or as inputs for other data such as bilge alarms or hatch positions, etc. There are 3 inputs capable of monitoring tank levels.

The CLMD16 handles many DC load types such as lights, pumps, motors, and electronics. An added benefit of the CLMD16 is that it reports the current through each of the 16 breakers. This allows you to determine if loads are drawing too much or too little electrical current. This information can be used to report overcurrent faults and under-current conditions such as burnt-out bulbs.

Remote control of navigation lights and boarding lights. Control of area lights with dimming. Burnt out bulb alerts.

• CLMD16 Load Module with a 1m mating connector for both the J1 and J2 connectors and a 1m I/O harness kit for the J3 connector.

The Maretron M-Power CLMD16-R DC Load Module is a 28-channel NMEA 2000(R) interface device designed for managing DC loads in IT and marine environments. This module provides sixteen dimmable Electronic Circuit Breakers (ECBs) for on/off control via an NMEA 2000(R) network. Four breakers support up to 25 Amps, while the remaining twelve handle up to 12 Amps, with a total current capacity of 125 Amps. It is suitable for applications requiring remote control and monitoring of various DC load types, including lights, pumps, motors, and electronics.

Key features include individual breaker electrical current monitoring, configurable power-up states, and the ability to lock breakers against inadvertent actuation. The CLMD16-R also offers eight discrete digital input channels, two resistive analog input channels, and one 4-20mA current loop input channel. Its IP67 rating and ignition protection make it suitable for demanding conditions, while opto-isolation from the NMEA 2000(R) network helps prevent ground loops. This module addresses the need for centralized, intelligent DC load management and fault detection.
