EMU-1 NMEA 2000 Engine Monitoring Unit

Modernize your vessel's engine monitoring system with the Actisense EMU-1-BAS Engine Monitoring Unit. Designed to connect traditional analogue engine gauges and sensors to a modern NMEA 2000 network, the EMU-1 converts engine data into digital NMEA 2000 messages, allowing vital engine information to be displayed across compatible multifunction displays, chartplotters and marine instruments.

The EMU-1 can monitor essential engine parameters including RPM, temperature, pressure, fluid levels and alarm conditions without requiring replacement of existing engine gauges or sensors. It supports inputs from up to two engines sharing a common ground, making it an ideal solution for upgrading both single and twin-engine installations.

Key Features:

• Converts analogue engine signals into NMEA 2000 data
• Supports monitoring of up to two engines sharing a common ground
• 6 analogue gauge / parameter inputs
• 4 alarm inputs
• 2 tachometer inputs
• 2 auxiliary inputs for additional monitoring flexibility
• Automatically records engine operating hours using tachometer inputs
• Compatible with a wide range of engine senders and gauges
• Configurable for different engine types and installations
• NMEA 2000 network connectivity with standard Micro-C connector
• Galvanically isolated NMEA 2000 interface
• Diagnostic LED indicators
• Wide operating voltage range of 9–35 VDC
• Protective IP-rated enclosure with splash-resistant connections
• Pluggable screw-terminal connectors for straightforward installation
• Optional DIN rail mounting kit available

Applications:

• Converting traditional analogue engine instrumentation to NMEA 2000
• Displaying engine RPM, temperature and oil pressure on modern multifunction displays
• Monitoring fuel, water and other fluid levels
• Integrating engine alarms into a vessel's NMEA 2000 network
• Recording engine operating hours
• Upgrading existing marine engine installations without replacing original gauges
