5SHY3545L0010  3BHB013088R0001 Anti-Jamming PLC Control System

5SHY3545L0010 3BHB013088R0001 anti-interference design of the control system. With the rapid development of industrial automation technology, thyristor controlled rectification and frequency conversion speed control devices are increasingly widely used, which brings the pollution of the AC power grid, but also to the control system has brought many interference problems, anti-interference is a PLC control system design must be considered. As the high-frequency interference in the grid is mainly distributed capacitance coupling between the primary and secondary windings, so it is recommended to use 1:1 super-isolation transformer, and the neutral point by capacitive grounding.

5SHY3545L0010 3BHB013088R0001 is generally shielded with a metal enclosure and the PLC system is built into the metal cabinet. Reliable grounding of the metal cabinet shell, can play a good static electricity, magnetic field shielding effect, to prevent space radiation interference. Strong power lines, weak telecom signal lines separate routing, and there should be a certain interval; analog signal transmission lines using twisted-pair shielded cable.
