The application is to connect to a typical ship’s RPM indicator, thruster,
rudder angle and telegraph. The voltages are turned into digital data for use by
a VOYAGE DATA RECORDER or the PORTABLE PILOTAGE AID.
The KW935 can be connected to any other AMI interface such as the KW910
synchro rudder angle interface or the KW991gyro and SMIDS instrument. Several
KW935s may be used, with a variety of connections, including the data combining
function of the KW909 interface.
The KW935 has four DC voltage input channels, isolated from
ground and from each other. Typical inputs may vary up to +/- 50 volts and be
either a single + or – polarity or both. The input circuit has a setting
potentiometer with a circuit to smooth out 50/60 Hz mains hum and switching
transients.
Non linear signals are easily taken care of by the microprocessor. Facilities are
built in to set up and check the system.
