Abstract

The invention provides a network relay control device which comprises a network relay, a surge protector and a PLC, wherein the network relay is installed on one side of the surge protector; the PLC is connected with the power supply end of the network relay; the surge protector is connected with the network relay; and the surge protector is connected with a reset line from a cabin. The PLC is further connected with a background server through a network cable; the network relay is used for receiving a fan motor starting signal, a newly added forward contactor, a newly added reverse contactor,a direct-current power supply and a safety device; the output end of the network relay plays a switching role; and the background server sends an action command to the PLC through the optical fiber network to drive the network relay so as to control the action of the fan motor.

Description

technical field [0001] The invention relates to the technical field of industrial control, in particular to a network relay control device. Background technique [0002] Existing fans may need emergency stop and reset in case of emergency during operation. However, the existing hard-processed emergency stop and reset are likely to cause damage to the fan and shorten the working life of the fan. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to solve at least one of the technical defects. [0004] Therefore, the purpose of the present invention is to provide a network relay control device. [0005] In order to achieve the above object, an embodiment of the present invention provides a network relay control device, comprising: a network relay, a surge protector, and a PLC controller, wherein the network relay is installed on one side of the surge protector, The PLC controller is connected with the power supply terminal of the network relay, the ...
