Port provide the control signal to the load.Two kind of control signal
port:
Type 1
:
Dry connector without voltage.
Type 2
:
Port provide the signal with 220V voltage. If the current of
load is <0.2A, load can connect to the port directly.
If the current of load is >=0.2A, the AC contactor is required to
connected for the load.
