The NAC-2 Autopilot Computer is the brains behind your
Simrad autopilot system. It contains the electronics needed to operate a
hydraulic steering pump or mechanical drive unit, while also interfacing with
other components including heading sensors and rudder feedback units. The
NAC-2 was designed for boats up to ten metres (35 feet) in length and is
suitable for low-current pumps, mechanical drive units, or solenoid valves
(eight amps continuous/16 amps peak).
Key Features
- Reliable autopilot performance based on Simrad Continuum steering
technology
- Recommended for boats up to 10 metres (35 feet) in length
- Output of 8 amps continuous, 16 amps peak
- Clutch output (3 amps maximum)
- Compatible with low -current drive pumps, mechanical drives, hydraulic
linear drives, and solenoid valves
- Virtual rudder feedback for simplified installation aboard outboard and
sterndrive (inboard/outboard) boats
- Supports Simrad RF25 rudder feedback units
- Plug-and-play connectors for easy installation
- NMEA 2000? connectivity to heading sensors, rudder feedbacks, dedicated
autopilot controllers, and multifunction displays
Simrad Continuum steering technology
Every Simrad steering innovation builds upon a legacy encompassing over sixty
years of autopilot development, which continues today at Simrad Yachting?s
autopilot research hub in Norway. This legacy is exemplified by the Continuum
algorithm: the software that drives Simrad steering technology. Continuum brings
all those years of research and on-water experience to your helm, for a smart
pilot you can trust to take the wheel.
Standard Output
The NAC-2 Autopilot Computer is recommended for boats up to 10 metres (35
feet) in length. It delivers standard power output of up to eight amps
continuous and 16 amps peak, plus a clutch output; this is suitable to operate
low-current drive pumps including the Simrad RPU80, mechanical drives such as
the Simrad SD10, hydraulic linear drives such as the HLD350, and solenoid
valves.
Virtual Rudder Feedback
Simrad Virtual Rudder Feedback (VRF) technology eliminates the need to
install a separate rudder feedback unit aboard outboard and sterndrive
(inboard/outboard) boats. This reduces overall autopilot system cost and
complexity, and is ideal where a feedback unit is impractical due to mechanical
constraints.
Rudder Feedback Units
Rudder feedback units are sensors that connect to your rudder via a
mechanical linkage and continuously report actual rudder position to your
autopilot computer ? allowing the Simrad Continuum steering algorithm to make
the best-informed steering decisions possible. These sensors are typically used
on boats with inboard engines, on larger vessels, and in special applications
where Virtual Rudder Feedback may not be suitable. The NAC-2 supports SimNet or
NMEA 2000? connected Simrad RF25 feedback units, and resistive rudder feedback
sensors.
Easy Installation
Plug-and-play connectors facilitate easy installation, minimising the wiring
necessary to install your autopilot system. Industry-standard NMEA 2000?
networking offers simple connectivity to heading sensors, rudder feedback units,
autopilot controllers, and multifunction displays located anywhere on board.
