SIMRAD RI 9 RUDDER ANGLE INDICATOR
The RI9 is manufactured in non-corrosive aluminum with a nonreflective black finish.
It is designed to operate from both voltage and current signals. The RI9 can also operate from the earlier Robertson "Standard" rudder feedback units.
The indicator is made in standard modular size (144x144 mm) to match the standard of the Simrad autopilots
A separate PCB is mounted inside the indicator to convert the input signals for the indicator instrument. To select either voltage or current operation, a âjumperâ is plugged in the respective position. For voltage operation a jumper is available for inverting the feedback signal.
The instrument gives a continuous reading of the rudder angle up to 45 degrees on either side of the midshipâs position. (Other angles as optional). Both deflection and offset are adjustable on the PCB. Internal illumination can be adjusted by the dimmer control on the front.
The water tight construction allows bulkhead or desk mounting in exposed locations, such as bridge wings as well as wheelhouse and engine room. RI9 substitutes the Robertson RI40 and RI45 rudder angle indicators
