Actisense EMU-1-BAS Engine Monitoring Unit

The Actisense EMU-1 is a specialized analogue to NMEA 2000 Gateway, which converts data from analogue engine senders into NMEA 2000. The EMU-1 enables NMEA 2000 display devices to monitor the engine on a vessel.

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 engines makes and models. Capable of measuring a wide range of engine parameters, the EMU-1 reports how the engine is operating and shares the information across the network.

Designed to simplify the conversion of analogue engine parameters (e.g. Temperature, pressure, and RPM) into NMEA 2000 engine PGNs, the EMU-1 simplifies processes and reduces the number of input/output wires required at each engine. The EMU-1 also supports the conversion of analogue transmission parameters and battery status to the associated NMEA 2000 PGN's.

The two-part screw terminal connection system allows for an easy pluggable connection to an engine wiring harness.

Multiple engines are supported by the setting of the engine instance using the EMU-1 configuration tool. Currently, one EMU-1 per engine is supported. Support for multiple engines on a single EMU-1 is planned as a future firmware update.

The customized case ensures that the electronics are sealed while allowing quick access to the electrical connections.

An optional DIN rail mounting kit is also available. The kit is suitable for use with a top-hat rail, type EN 50 022 or a G section rail, type EN 50 035. Please order the DIN rail kit using part number: DIN-KIT-1.

It is strongly recommended to have an Actisense NGT-1 NMEA 2000 PC Interface available for every EMU-1 installation. The NGT-1 can be used to update the Firmware, connect the Configuration Tool and display data on a PC for diagnostic and information purposes using NMEA Reader. Please visit the NGT-1 page for product details.
