Raymarine iTC-5 Instrument Transducer Converter 

iTC-5 front view

Transducer signals are easily converted to SeaTalkng


The Raymarine iTC-5 converts analogue transducer signals used in i70, ST70+ and ST70 instrument systems to SeaTalkng



Transducer connections on the iTC-5    

Transducers for Speed/Temperature, Depth, Wind, Rudder Angle and Fluxgate Compass can be connected to the one iTC-5 unit, eliminating the need for multiple ST70 pods.


Extended STng systems can support multiple iTC-5 units.


SeaTalkng connections at the base of the unit simply connect the iTC-5 unit into the SeaTalkng backbone.


Please note the ST40/i40/i50/i60 and ST60+ displays cannot calibrate the iTC-5. Only the i70 has full transducer calibration. The ST70/ST70+ can calibrate the Depth, Wind and Speed/Temp transducers (not Rudder or Compass).


If you don't have an ST70/ST70+ or i70 in your system, then the ST40/i40/i50/i60/ST60+ displays must be interfaced directly to the relevant analogue transducers

Possible systems 


Note: In a SPX autopilot system the fluxgate compass and rudder reference transducer must be connected directly to the course computer and not the iTC-5.
