KW910-M Synchro Interface
The interface converts synchro transmission to NMEA 0183 or IEC 61162 data. Applications include
- Gyro compass for radar, ECDIS and heading displays.
- Rudder Sensor Angle used with a VDR.
- Telegraph, pitch, rudder demand;
The “XDR” sentence can be used for many synchro systems.
- Wind speed and direction
- Log speed
The interface is a precision device, and does not require alignment in the 1:1 mode. The interface can convert gyro ratios such as 90:1. A DIP switch selects reference voltages over the range of 40 to 220 and signals from 40 to 90. The function & choice of data output is set by a 2nd DIP switch.
Synchro 40 to 550 Hz. Reference 40 to 220v. Phases 40 to 90 volts.
Loading resistors 91K to 270K ohm per phase. 22K reference.
The phases have a common connection at centre of the three phase scaling resistors to the power input 0v. Reference input is isolated by transformer.
We can supply KW910’s for voltages outside the range mentioned and for extreme precision.
Conversion 12 bits, 0.1 degrees.+/- 0.5 degrees. Conversion rate 40 per second.
