Simrad PRO RF14XU Electronic Module

The Simrad Pro RF14XU RF module is a rudder feedback unit designed to provide accurate rudder position data to Simrad autopilot systems and rudder angle indicators. It is a critical component for the operation and accuracy of these systems.

The RF14XU module generates two types of signals:

A variable-frequency signal for Simrad autopilots. A voltage signal proportional to the rudder angle for indicators.

The RF14XU module is designed to be compatible with Simrad autopilot systems, including the Simrad AP50 autopilot, as stated in the technical documentation. It is generally compatible with Simrad autopilots that use variable-frequency rudder feedback signals.

The RF14XU RF module housing is made of flame-retardant fiberglass-reinforced polyester. It also includes an aluminum mounting plate designed to resist seawater, ensuring durability in the marine environment.

The RF14XU module is designed for signal control over a ±90-degree range relative to the rudder’s mid-position. This allows it to detect a wide range of helm movements.

The RF14XU (SKU 22501605) is specifically the electronic module of a rudder feedback unit. It is classified as an active spare part (« Spare Active ») and is part of the complete rudder feedback unit RF14XU (SKU 22506950).

The RF14XU module contains a potentiometer, which is a key component. It is responsible for measuring the physical position of the rudder and converting this position into an electrical signal, which is then processed by the module to generate frequency and voltage signals.

For rudder angle indicators, the RF14XU module outputs a voltage signal. This signal is proportional to the rudder angle and varies by ±9 volts around half the supply voltage, enabling clear and precise display of the rudder position.

When the rudder is in the midship position, the RF14XU module generates a 3400 Hz frequency reference for Simrad autopilots.

The variable signal frequency changes by 20 Hz per degree of rudder movement. This frequency increases when the rudder moves to port, providing a dynamic and precise indication of the helm angle to the autopilot.

The RF14XU module is a precision electronic component designed for marine navigation systems. Although it is built to integrate with existing Simrad systems, its installation and calibration typically require specific technical knowledge in marine electronics. It is recommended to use a professional to ensure correct and secure installation.

The RF14XU module is specifically designed to operate with Simrad autopilot systems, using proprietary signaling protocols. Compatibility with systems from other brands is not guaranteed and is generally not recommended due to potential differences in signal requirements and interfaces.

The RF14XU electronic module integrates several key components for its operation. It includes a potentiometer for position detection, limit switches for rudder angle limits, and an electronic drive module that manages the generation of output signals.

Yes, the RF14XU module operates with a supply voltage. The voltage signal it outputs for rudder angle indicators is also proportional to this supply voltage, varying by ±9 volts around its midpoint.

The limit switches integrated into the RF14XU module detect the extreme positions of the rudder movement. This allows the autopilot system to know the physical limits of the tiller and prevent excessive movements.

Yes, the RF14XU module is a key component of a rudder position sensor, or rudder feedback unit. Its primary role is to electronically detect and transmit the rudder's angular position to navigation systems.

The RF14XU module is the electronic unit itself. The specific connection cables required for integration into an autopilot system are usually sold separately or included in the complete installation kit for the rudder feedback unit.

The RF14XU module significantly improves autopilot accuracy by providing real-time, highly precise data on the rudder’s exact position. This allows the autopilot to quickly and effectively adjust the vessel’s heading, enhancing course-keeping and fuel efficiency.

Yes, thanks to its robust construction, including a non-flammable polyester housing reinforced with glass and a seawater-resistant aluminum mounting plate, the RF14XU module is designed to withstand the demanding conditions of the marine environment.

The RF14XU RF module weighs approximately 0.499 kg (about 500 grams).
