RI35 Mk2 Rudder Angle Indicator

The RI35 Mk2 is manufactured in non-corrosive aluminum with a non-reflective black finish. It is designed to operate from frequency or current signals generated by a Simrad autopiloy feedback unit. It will also accept a NMEA 0183 rudder angle (RSA) signal. The indicator is made in standard modular size (132 x 108mm) to match the Simrad AP35 autopilot. A separate PCB is mounted inside the instrument to convert the input signals and drive indicator.

The instrument gives a continuous reading of the rudder position up to 45° on either side of the midship's position. With no signal input the pointer moves out of scale to port. A front key panel is used for illumination and setup adjustments. The splash proof construction allows panel, bulkhead or bracket mounting in exposed locations, such as bridge wings as well as wheel house and engine room.
