Simrad AC70 Course Computer — Product description

Navigating challenging waters demands equipment that stands up to constant exposure to salt, waves, and extreme conditions. The Simrad AC70 Course Computer steps in as a reliable backbone for professional autopilots like the AP70 and AP80 systems, delivering precise control over your vessel's steering. Engineered for rudders driven by reversible motors or non-isolated solenoids, this drive computer processes frequency-based rudder angle feedback to ensure steady, responsive performance on long hauls or in rough seas.

Core Features of the Simrad AC70

  • Robust Drive Control: Handles reversible motors or non-isolated solenoids seamlessly, providing the muscle for hydraulic steering setups common in commercial and workboats.
  • Precision Feedback: Integrates frequency rudder angle sensors for accurate position tracking, minimizing drift and enhancing course-holding even in crosswinds or currents.
  • NFU Connectivity: Supports Non-Follow-Up remote controls, giving operators quick manual override options from the helm or flybridge.
  • NMEA Communication: Features a single-channel IEC 61162-1 (NMEA 0183) RX/TX port, with compatibility for protocols 61162-1, 2, and 3, allowing integration into broader navigation networks for data sharing on heading, wind, and GPS inputs.
  • Power Versatility: Operates on 12-24V DC systems with a 30-amp maximum draw, fitting a wide range of vessel electrical setups.

Why Boaters Trust the AC70 for Demanding Operations

In the world of marine electronics, reliability isn't optional—it's essential. This course computer shines in high-stakes environments, from offshore fishing charters to supply vessels, by offering stable autopilot performance that reduces crew fatigue during extended voyages. Its compact design simplifies retrofits into existing AP70/AP80 systems, while the built-in safeguards against power surges protect your investment in harsh saltwater conditions.

Users report smoother rides with less rudder hunting, thanks to the optimized processing of rudder feedback signals. Pair it with Simrad's ecosystem, and you unlock layered automation: wind vane steering modes, route following, and adaptive gain adjustments that learn your boat's behavior over time.

Complete Kit for Seamless Setup

Every AC70 package equips you with essentials for straightforward installation:

  • T-Connector for easy network integration.
  • 2-meter power network cable with terminator to maintain signal integrity.
  • 0.6-meter pigtail male connector for quick solenoid or motor hookups.

These components cut down wiring hassles, letting installers focus on calibration rather than fabrication.

Pro Tips for Optimal AC70 Performance

Mount the unit in a dry, ventilated spot away from engine heat. During commissioning, zero in on rudder feedback calibration using your vessel's full lock-to-lock travel—this ensures the autopilot compensates accurately for your hull's hydrodynamics. For multi-station helms, leverage the NFU port to sync joysticks without signal conflicts. Regularly inspect connections for corrosion, a common culprit in marine setups, to sustain peak efficiency.

Frequently Asked Questions

What types of steering systems is the Simrad AC70 compatible with?

The AC70 works with rudders using reversible motors or non-isolated solenoids, paired with frequency-based rudder angle feedback sensors. It's ideal for hydraulic rams in professional autopilots.

Does the AC70 support NMEA data integration?

Yes, it includes one NMEA 0183 (IEC 61162-1) RX/TX channel, compatible with protocols 61162-1, 2, and 3 for sharing data like GPS waypoints and wind angles with other instruments.

What power requirements does the AC70 have?

It operates on 12-24V DC power supplies, with a maximum current draw of 30 amps, making it versatile for various boat electrical systems.

Can I connect non-follow-up (NFU) controls to the AC70?

Absolutely. The unit features a dedicated connection for NFU remote controls, enabling manual steering overrides from multiple stations.

Is the AC70 suitable for commercial vessels?

Designed for the harshest marine environments, it's proven in professional applications like the AP70 and AP80 autopilots on workboats and larger crafts.

What cables come with the AC70 Course Computer?

Included are a T-Connector, a 2-meter power network cable with terminator, and a 0.6-meter pigtail male connector for plug-and-play installation.

How does frequency rudder feedback improve autopilot performance?

Frequency feedback provides real-time, high-resolution data on rudder position, reducing overshoot and improving course stability compared to analog potentiometers.

Out on the water, the gear you run could make all the difference. With our high-performance products proven in the harshest of environments, Simrad ® will get you there like no one else. We give you a comprehensive portfolio of precise and responsive technology for a complete experience.
