An electric operator which can make Ethernet on communication and be power-supplied by network redundancy includes microprocessor which is connected separately with latch, program storage, data storage, A/D converter and driving amplificatino circuit which is connected with deccelerator via servo motor, and position sender set up between A/D converter and deccelerator. It works as follows: the microprocessor is connected to a sending-receiving controller of Enthernet signal, and thers is programmable logic array circuit in-between; the sending-receiving controller is also connected with RJ 45 interface and DC/DC voltage converter which is connected to related circuits, there is power redundant input circuit between RJ 45 and DC/DC voltage converter. |
