RF45X Rudder Feedback Unit
This rudder feedback unit with T45 transmission link and 2 m (6
feet) of cable transforms the angular travel of the rudder to a
digital signal read by the autopilot steering computer. It is to be
used on medium to large size vessels.
RF14XU Rudder Feedback Unit
This unit can replace the RF45X Rudder Feedback Unit in
installations where a more rugged construction of the feedback
unit is preferred. Besides electronic circuitry to generate
feedback signals for the autopilot and rudder angle indicators it
has been provided with 2 sets of limit switches.
1.7 Heading Sensors
The AP50 autopilot system can be used with the following
combinations of heading sensors:
RC25/RFC35R Rate Compass
The fluxgate compass with an integrated rate of turn sensor
provides a dramatic improvement to the dynamic performance of
both the autopilot and any stabilized radar display.
CD100A Course Detector and CDI35
Course Detector Interface
The sensor and interface unit connects the AP50 system to a
magnetic compass. The AP50 provides excitation current for
CD100A and converts the analog sine/cosine signal to digital
two-wire format for the autopilot steering computer.
General NMEA Compasses
Any compass outputting a NMEA 0183 message with either
HDT, HDG, or HDM sentence can be connected directly to the
J50/J50-40 junction units or to the NI300X NMEA Interface. An
output of 10 Hz is recommended.
HS50 GPS Heading Sensor
The Simrad HS50 is a GPS compass that displays true heading
output with position, velocity, and rate-of-turn information. This
product replaces several vessel instruments in one compact
package (gyrocompass, GPS system, and speed input).
The HS50 comprises three components: the sensor unit, the
interface unit, and the display unit.
