The RF14XU Rudder Feedback Unit consists of a glass reinforced non-flammable polyester housing with a mounting plate of sea-water resistant aluminium. It contains a potentiometer limit switches and an electronic drive module. The electronic drive module contains a voltage section and a frequency section.
The voltage section outputs a voltage to the rudder angle indicator(s) which is proportional to the rudder angle. The voltage varies ±9 volts around half the supply voltage.
The frequency section generates a variable frequency signal with 3400 Hz as midposition reference. This section is only used if a Simrad autopilot is connected to RF14XU. The signal varies at a rate of 20 Hz/degree increasing when the rudder moves to port and vice versa. The shaft of the Feedback Unit is free to travel 360 degrees but only ±90 degrees from midposition are used for signal control. RF14XU is equipped with two sets of micro switches which can be used as electrical limit switches for the steering gear.
The rudder feedback unit transmits a signal proportional to the rudder angle. It is mounted close to the rudder stock and is mechanically connected to the rudder by a transmission link in a 1:1 ratio.
