Detailed description
Detailed description
Designed for integration with SimNet networks, the Simrad RF25 Rudder Feedback - SimNet is a rudder angle feedback unit for autopilot systems. It converts the mechanical angular movement of the rudder into a digital signal transmitted via the SimNet/NMEA2000 network.
Integration and performance
The RF25 is powered via the SimNet network (8-16V) with low power consumption of 0.4W. It features a single SimNet port for input and output, with a network load factor (NL) of 1. This sensor measures rudder angle up to ±120 degrees, with an accuracy of ±0.25° within ±5°, and ±0.5° beyond. Its repeatability is ±0.1°.
Design and installation
Made from Arnite T06 200 PBT, the RF25 weighs 0.5 kg. It can be mounted horizontally, vertically, or upside down. The stainless steel linkage rod measures 345 mm and includes two ball joints. The unit is designed for direct mechanical connection to the tiller arm or quadrant. Its waterproof rating is IP56.
Environment and compatibility
The RF25 operates in a temperature range of -25 to +55 °C and can be stored from -30 to +70 °C. It is NMEA compliant and continuously transmits rudder angle (PGN127245), even when the autopilot is disabled. The unit is factory-calibrated and typically does not require additional calibration after mechanical installation.
