Simrad RF14XU Rudder Feedback Unit - 22506950

Simrad RF14XU Rudder Feedback Unit - 22506950

RF14XU Heavy Duty Rudder Feedback Unit, PCB w/ Transmission Linkage 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.

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.

Features:

• Long life feedback unit with transmission linkage.
• Separate output for rudder angle indicators.
• Double set of limit switches.
• Requires 24VDC supply voltage.
