Embodiment 2
[0075] In the second embodiment, when the normally open contact of the relay J is closed, the light-emitting diode in the photocoupler U2 has current and emits light, the phototransistor in the photocoupler U2 is saturated and turned on, and the output V+ of the voltage stabilizing circuit 7 passes through the resistor R4 Loaded to the emitter of the transistor T; when the normally open contact of the relay J is released, the light-emitting diode in the photocoupler U2 has no current and does not emit light, the photosensitive transistor in the photocoupler U2 is cut off, and the output V+ of the voltage stabilizing circuit 7 is cut off to The emitter path of the transistor T.
[0076] A method for controlling a power plug-in device, the main features of which are as follows:
[0077] a) The power supply of the mainframe computer is inserted into the first socket 10 on the power strip device, and the power supplies of the display, printer, and scanner are arbitrarily inserted ...
