Application of Network Control Technology in Vulcanizer Control System The vulcanizer control system adopts network control. Guilin Rubber Machinery Factory mentioned it around 1995. At that time, it could not be realized due to the limitation of the programmable logic controller (hereinafter referred to as PLC) network system and various reasons. In view of the various defects of the recording co...
Processing of power supply by PLC Power supply is one of the main ways for interference to enter the programmable controller. Power supply interference is mainly generated by impedance coupling of power supply lines, and various high-power electrical equipment is the main source of interference. In situations with strong interference or high reliability requirements. A shielded isolation tra...
The low-pass filter can absorb most of the " burrs " of the power supply . L1 and L2 in the figure are used to suppress high-frequency differential mode voltage . L1 and L2 are reversely wound on the same magnetic ring with equal-length wires , 50HZ The magnetic fluxes generated by the power frequency current in the magnetic ring cancel each other out, and the magnetic ring will not be saturated.&...
