Zusammenfassung: | The invention discloses a contact-less contactor capable of realizing pointing control and belongs to the technical field of contact-less contactor control. The contact-less contactor capable of realizing the pointing control comprises a main contact connected in three-phase alternating current in series and is characterized in that any two phases are led out from the three-phase alternating current to serve as a drive power supply connected to the input end of a first conditioning module, a main contact drive module is connected with the main contact to drive the main contact to act, a switch module capable of being manually turned on and off is arranged between the first conditioning module and main contact drive module, and control signals output from a field controller are simultaneously accessed into the switch module to realize the automatic on and off of the switch module. By means of the contact-less contactor capable of realizing the pointing control, the pointing control for any point can be realized in the industrial field, the on-site local debugging and maintaining are facilitated, and the debugging process is not influenced by original control signals. |
