5.4.4. ECAN-PCB for engine with CANBus interface
Important:
you need a CANBus board per each CANBus engine
The out-coming cable has a length of 3, 5 or 7 meters (section 6.2.8). Maximum
current per each channel is 100 mA.
Can_H and Can_L signals are protected against short circuit towards ground
and towards power supply.
CANBus termination resistor of 120 ohm is already mounted on the PCBoard (between terminals 4 and 5 of
J4) but, if necessary, it can be removed; if this is the case, contact Flexball technicians.
5.4.5. Galvanic insulation PCB for analogue voltage signals
This option can be used in those cases where there are voltage differences between different ground points
on the boat. A non optimum ground network can generate circuit currents and therefore disturbances in the
transmission of command signals (see section 10.1.6.).
Each PCB performs the galvanic insulation of 2 command signal up to 250 Vdc. On each actuator it is possible
to mount 2 PCBs for the interface towards:
electronic ECU with voltage signal
electronic ECU with CANBus interface
frequency converter driven through a voltage signal, in case of hybrid propulsion systems
