Simrad A2004 – Autopilot Pack No Compass

Description

The Simrad A2004 Autopilot Pack without Compass is a professional autopilot package for compatible commercial and larger-vessel steering systems. It includes the A2004 color autopilot control display, AC70 high-current course computer, and RF300 mechanical rudder-feedback unit. A heading sensor or compass is not included, and the package also requires a separately selected steering drive, pump, solenoid system, power circuit, and vessel-specific installation components.

The AC70 supports 12V or 24V installations and provides up to 30A continuous output with up to 50A short-duration peak capacity for compatible steering drives. The RF300 supplies physical rudder-angle feedback through its mechanical linkage, while the A2004 provides a dedicated rotary-dial and color-display control interface. Add a compatible Precision-9, GPS compass, gyrocompass, or other approved heading source before commissioning the autopilot.

Key Specifications

• Professional Simrad autopilot package with A2004 controller, AC70 course computer, and RF300 rudder-feedback unit.
• Supplied without a compass or heading sensor.
• Requires a separate compatible heading source, steering drive, pump, solenoid system, power circuit, and installation hardware.
• Supports 12V or 24V DC installations.
• The AC70 provides up to 30A continuous output and up to 50A short-duration peak capacity.
• The RF300 provides physical rudder-angle feedback through a mechanical linkage.
• Supports compatible reversible hydraulic pumps, solenoid valves, and approved professional steering systems.
• Uses NMEA 2000 and NMEA 0183-compatible integration through the complete installed system.

System Integration

This pack cannot operate as a full autopilot until a compatible heading source is added. The RF300 measures rudder position, not vessel heading. Select the heading sensor according to required accuracy, vessel type, installed navigation network, class requirements, and compatibility with the AC70 and A2004 system.

Match the steering drive to vessel displacement, hydraulic-cylinder volume, steering-gear type, pump flow, motor or solenoid current, duty cycle, and required rudder force. The AC70’s maximum output should not be used as a generic drive recommendation without confirming the selected steering equipment and supply wiring.

Installation Considerations

Mount the A2004 at the helm or bridge, place the AC70 in a dry accessible location with adequate ventilation and high-current wiring clearance, and install the RF300 near the rudder post or tiller arm with free mechanical linkage movement. Add and correctly position the heading sensor, then verify steering direction, rudder feedback, alarm functions, network communication, and sea-trial performance during commissioning.

Before Ordering

Confirm a compatible external heading sensor, selected hydraulic pump or solenoid steering system, drive current within AC70 capacity, hydraulic-cylinder volume where applicable, RF300 mounting geometry, 12V or 24V supply, NMEA 2000 and NMEA 0183 requirements, A2004 panel space, AC70 protected mounting location, wiring and circuit protection, and complete autopilot-system components before purchase.
