The rudder feedback units consist of aluminum housing and are available as medium or heavy-duty versions. The output can be connected to the analog module. The rudder feedback units contain a potentiometer, which is proportional to the rudder angle. Next to this, the heavy-duty version contains additional limit switches.
The rudder feedback units can be mechanically coupled to the rudder post by chain or a transmission link. The continuously transmitted accurate rudder angle data will be received by the analog interface. It converts the analog signal to a digital Modbus and IEC61162-1 signal and can be transmitted to any AlphaLine Repeater display capable of displaying graphical rudder information.
