Simrad Rudder Reference Series.

Simrad Rudder Feedback Units

Product Description

Simrad offers a series of medium-duty rudder feedback units engineered to provide precise, high-resolution rudder angle data necessary for accurate autopilot operation. These rugged units are designed to perform reliably in harsh maritime environments and support a range of Simrad autopilot systems.

Models include the RF45X, a mechanically repairable unit with pulse width modulated frequency output compatible with different autopilot inputs (AP35/AP50, AP45, AP9 Mk3) and operable at 24V DC, making it suitable for standalone rudder angle indicators. The RF25 features a SimNet interface for straightforward connectivity to SimNet systems, while the RF300 offers a direct 2-wire frequency interface connection to autopilot computers.

These feedback units enhance vessel steering by providing vital rudder position information, ensuring smooth, responsive, and safe autopilot control.
