| Zusammenfassung: | The utility model provides an anti-interference remote switch controller, which comprises a switch control circuit and a power supply output circuit used for supplying power to the switch control circuit, the power supply output circuit comprises a plurality of power supply output ends, and a main control chip, an RS485 module and a relay are respectively connected to different power supply output ends; the relay is a magnetic latching relay; and the signal end of the main control chip is connected to the RS485 module through the photoelectric coupler. According to the utility model, the 485 communication chip, the main control chip and the relay are respectively powered by different power supplies, and the signal transmission of the 485 communication chip and the main control chip is isolated through the photoelectric coupler, so that the anti-interference performance of the whole controller is improved. Besides, the relay is a magnetic latching relay, and the relay only consumes power at the moment of switc |
