The power supply voltage of controller is DC9~24V, which can be powered
by terminals or DC plugs. Determine the positive and negative electrodes
according to the film and PCBA logo.
After power cable is connected normally, PWR light of the controller is

to the power input interface, and any set of interfaces can also supply power to
the device or active sensors.
