Description
The EmpirBus NXT DCM (DC Module) is the workhorse of an EmpirBus NXT digital switching installation, connecting directly to the main DC power and turning network commands into real electrical outputs. Each module carries 16 universal, user-configurable bi-directional channels wired through two Molex MX150L connectors, so a single compact unit can both drive loads and read inputs.
Every output is electronically protected with programmable fuse sizing, under-current detection and soft start/stop, and can dim or sequence complex loads such as LED lighting and windscreen wipers directly. High-side and low-side switching simplify wiring, while channels may be paralleled for higher current. Configured as inputs, channels accept volt-free switches, multiplexed switches and analogue voltage, current or resistance signals. Communicating over CAN-bus NMEA 2000, the DCM lets the EmpirBus system replace conventional fuse boards and switch panels with intelligent, monitored control.
