Hello,
I’ve a little question about the transmission of electric power through the main tank. Most of you have 4 power connections.
I’m surprised about it, why do you need 4?
For my Victoria class project I hesitate between two solutions:
1) Only 2 electric power connections (0 and +12V for the compresseurs). In this case the 24V signal for the valves ( Danfoss valves for the ballast and pneumatics valves) circulate directly in the D-Sub.
2) 3 electric power connections (0, 12 and 24V). In this case the signals for the valves circulate in the D-Sub but they are only control signals. Those signals are controlling relays which switch the 24V power current from the power connections to the valves .
(I'm not sure to have been realy clear. If necessary i can draw a schema.)
On your models, why do you have 4 electric power connection?
Thank you for your help
Pierre
