EMU-1-BAS Analogue Engine to NMEA2000 converter

The Actisense EMU-1 is a specialized analogue to NMEA 2000 Gateway which converts data from analogue engine gauges/senders into NMEA 2000 data. The EMU-1 enables the sharing of engine data throughout the NMEA 2000 bus. It digitises analogue engine sensors, enabling NMEA 2000 display devices to monitor the connected engine(s) on a vessel. The EMU-1 can monitor vital engine parameters such as temperature, pressure RPM and fluid levels from up to two engines.

EMU-1 Engine Monitoring Unit

The EMU-1 has a PC based configuration tool that allows the settings inside the EMU-1 to be changed to best suit the engine it is working with, making it a flexible solution for many engine makes and models. An Actisense PC to NMEA 2000 Gateway (NGT-1) is required to configure the EMU-1.

It is recommended that an NGT-1 is available for every EMU-1 installation. The NGT-1 can be used to update the firmware, connect the Toolkit and display data on a PC for diagnostic and information purposes, using NMEA Reader. Please visit the NGT-1 page for product details.

FEATURES

  • Enables analogue signals to be converted to NMEA 2000 messages
  • Convert signals from up to two engines (that share a common ground) with a single EMU-1
  • 6 gauge / parameter inputs
  • 4 alarm inputs
  • 2 additional auxiliary inputs
  • 2 Tacho inputs
  • Customised IP65 case
  • Diagnostic LED’s
  • Wide power compatibility of 9 to 35 Vdc

BENEFITS

  • No need to change an existing engine
  • Easy installation
  • Easy to configure to suit the connected engine
  • Connect signals from fluid level gauges (that share a common ground with the engine) to NMEA 2000®
  • Optional DIN rail mounting kit available
  • Total engine hours are logged by the monitoring of engine Tach (RPM) input
