Description
Professional Interface and Processor Analysis
Commercial maritime operations requiring heavy-duty drive capacity often already possess high-accuracy NMEA 2000 heading sensors. The Simrad A2004 Autopilot Pack (No Compass) provides the industrial-grade A2004 control head and NAC-3 processor for existing networks. This system manages high-current hydraulic pumps and solenoids.
The A2004 display features a dedicated rotary dial and hardware buttons for tactile command in extreme weather. Integration occurs via the NMEA 2000 backbone to synchronize external sensor data with the high-current computer. The optically bonded glass meets IPX7 standards to prevent internal moisture fogging in open console environments.
Strategic Vessel Application
Optimized for commercial workboats already equipped with a rate compass or satellite compass requiring a professional autopilot core.
