EmpirBus NXT DC Module

The NXT DC Module (DCM-11) is an IP65 rated NMEA2000 device that is connected to the main DC Bus and provides inputs and outputs to the system. Physically the DCM is a compact, easily mounted, 16 channel device, featuring two 16 way Molex MX150L connectors which form the user interface, each channel has a both a positive and negative connection. The main DC Power is connected by two M6 studs. In addition there is also a slot for a GSM SIM Card (optional), Ethernet connection (optional) and GSM Antenna (optional).

All output channels are electronically protected and feature undercurrent protection as well as soft start / stop and are capable of being electronically dimmed and of driving complex loads such as LED lighting or Windscreen Wipers directly. To increase output capacity outputs may be paralleled and to simplify installations both High Side and Low Side switching is possible.

With multiple input capabilities and ranges the DCM is an extremely versatile and cost effective means to interface signals to the system and when combined with the powerful NXT software complex monitoring and control systems are easily realized in practice.


The DCM-11 (2010101-1000) is a basic DC module with the following features:

  • Operation 12 VDC
  • (16) Digital inputs
  • (12) Output 12 V, 10 A
  • (0) Output 12 V, 18 A
  • (0) Output minus
  • (2) Commonline for running indication LED
  • (8) Dimmer/PWM
  • (0) Volt/resistance input
  • (0) Analog input 4-20 mA 
  • (0) Wiper synchronization
  • Limp Home-funcionality
