Abstract
Disclosed in the utility model is a programmable logic controller (PLC) protection apparatus of a twisting system of a spinning machine. The PLC protection apparatus comprises a solenoid valve, a programmable logic controller, and a relay protection apparatus; the solenoid valve is connected in series with the programmable logic controller; the relay protection apparatus is connected in parallel with the programmable logic controller. Because the relay protection apparatus is connected in parallel to the programmable logic controller (PLC), the impact on a PLC contact by the starting current of the solenoid valve can be reduced, so that the PLC can be effectively protected and the PLC is not influenced; and the PLC can work stably, the service life is prolonged, and the fund waste can be reduced. Moreover, the relay protection apparatus can be assembled simply and can be operated simply; and automatic adjustment of an electric power system under the circumstances that the voltage is not stable can be realized.
Description
Technical field
The utility model is specifically related to a kind of PLC protective device of spinning frame twist system.
