Actisense EMU-1 BAS - NMEA 2000 Engine Monitoring Unit
Product Overview:
The Actisense EMU-1 Engine Monitoring Unit shares vital engine information on the NMEA 2000® bus by digitizing analogue engine sensors. This flexible unit can be configured to suit the engine it is working with, making it an ideal solution for various engine makes and models. It is capable of reading a wide range of engine parameters, reporting on engine performance, and sharing this information across the network.
Key Features:
- Enables analogue signals to be converted to NMEA 2000® messages.
- Upgrades older engines for compatibility with the latest digital MFDs.
- Can convert signals from two engines (with a common ground) using a single EMU-1.
- Six gauge/parameter inputs for connecting to resistive/voltage gauges or resistive senders.
- Four alarm inputs that connect directly to alarm switches or gauge signals, mapping them to NMEA 2000 alarms.
- Two Tacho inputs for connecting directly to RPM signals from one or two engines.
- Two additional auxiliary inputs for future expansion opportunities.
- Customized case protects electronic parts and connections.
- Input protection safeguards against reverse polarity and transients.
- Wide power compatibility of 9 to 40 VDC for use on most common power systems.
- Bulkhead mountable, with an optional DIN rail mount kit.
- Total engine hours are logged by monitoring the engine tach (RPM) input.
- Accumulated engine running hours are stored and shared as NMEA 2000 data.
