Features: This programmable logic controller uses industrial-grade 32-bit MCU with strong anti-interference and faster speed. The PLC board directly uses GX programming software for ladder diagram, written to the PLC directly, can monitor online. It supports super encryption, as long as input password under PLC state, there is no read function. Stable and reliable performance, build-in watchdog timer circuit, effectively ensures module long time work. Widely used in all kinds of industrial automatic control, such as metallurgy, chemical, plastics, textile, food, packaging, printing, building materials, carpentry, central air conditioning, environmental protection equipment and industrial single process control equipment in industrial assembly line, various kinds of machine tools.
