Страница: 15 / 116

RAIS 056357/B
RAIS Technical Data 1-7
RAC Signal and Data Inputs
rudder angle feedback input Wiper signal from rudder angle
feedback potentiometer;
±15 VDC supply voltage provided
by RAC.
RS-422 input NMEA 0183 / IEC 61162;
other side’s rudder angle in dual
rudder systems ($--RSA)
RAC Signal, Data and Status Outputs
analogue rudder angle outputs
(6x) six independently calibratable
voltage outputs to moving-coil
rudder angle indicators,
±15 VDC max. into 10 k

RS-422 output 1 IEC 61162 (NMEA 0183),
4800
9600 or
38400 Baud*
rudder sensor angle ($--RSA)
RS-422 output 2 IEC 61162 (NMEA 0183);
4800
9600 or
38400 Baud*
rudder sensor angle ($--RSA),
set alarm state ($--ALR)
CAUTION
Risk of misusage
The RS-422 output 1 and RS-422 output 2 of the RAC is not
MED compliant in case 38400 baud are selected as interface setting.
Always make sure that another baud rate setting (4880 or 9600 baud)
must be selected as RS-422 output 1 and RS-422 output, when the RAC is
used on a ship under wheelmark certification
