Select 2 cores for power supply only;
Select 4 cores for power supply + single-channel signal transmission;
Select 8 cores and above for multi-channel signals & intelligent diagnostic function.
Priority select 2~4 cores if single-core current demand > 3A;
Select 9~17 cores for low-current & multi-channel signal transmission scenarios.
Technical Note: Comprehensive judgment should be made combining signal channel quantity and current load demand, avoid blind selection of large core count to cause cost waste and wiring redundancy.
