HEADING REPEATER and OFF-COURSE ALARM.  KW991  KW991 DIGITAL HEADING REPEATER AND INTERFACE

Digital heading & rate of turn indicator
Tape repeater
Off-course alarm
Compass alarm
NMEA interface
Options: just you check!

Whenever a DIGITAL REPEATER WITH RATE OF TURN INDICATOR is called for think first of the KW991. It is ideal as the electronic alternative of the expensive inner and outer dial mechanical heading repeater. Trunnion or panel mounting.

 

DIGITAL WITH RATE OF TURN. Two scales of tape allows the instrument to be used for steering. 

Digital (numbers) displays can be difficult to steer by in rough seas, but the 991 has that too. Screen selection is by a tactile keypad.

TAPE DISPLAYThe instrument has a course-to steer and an off-course-alarm function to drive a 5 volt alarm or relay. A Compass Comparator alarm also available. 

The NMEA 0183 output means that you can use the 991 as a gyro converter to interface autopilots, radars and other instruments.

COMPASS COMPARATORA COURSE-RECORDER VDR version is available. The NMEA 0183 output is replaced by a plain text output to a low-cost dot matrix printer.
