Title:
ON-OFF CONTROL CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2018/233423
Kind Code:
A1
Abstract:
An on-off control circuit, which may implement the turning on and turning off of single and multiple dry node control circuits and achieve time division multiplexing of a same direct current (DC) power supply. When there are more than two dry node control circuits, an access port of one dry node control circuit is turned on, and the access ports of the other dry node control circuits are turned off, so that a relay connected to the on dry node control circuit is closed, and a DC level is outputted to a load port by means of the closed relay; when the access ports of multiple dry node control circuits are all turned on at the same time, each dry node control circuit is turned off according to the mutual restriction relationship among the dry node control circuits, and a relay connected to such circuit is always in an off state, so that a DC level could not be outputted to the load port by means of the relay.
