The LKC series PLCs are developed based on Hollysys' years of PLC R&D expertise, fully incorporating the latest advancements in international industrial electronics and industrial control technologies, while complying with internationally advanced industrial standards, safety design standards, and reliability design standards. They comprehensively address the requirements of both discrete control and continuous control, meeting application needs in multiple fields such as equipment automation and process automation. These PLCs are widely applied in national key sectors including hydropower, water resources, metallurgy, aerospace, and nuclear power.
The network communication protocol stack, embedded software, and programming software achieve 100% independence and controllability. The PLCs adopt the Loongson 2K1000 dual-core 1GHz high-performance industrial processor, with 100% independent and controllable hardware. They have obtained multiple authoritative certifications such as the Achilles Level 2 Certification and Network Key Equipment Security Certification (GB 40050), and support active protection for trusted computing. The system supports full redundancy configurations including CPU redundancy, power supply redundancy, and Ethernet redundancy. It features high reliability, with functions such as isolation, self-diagnosis, and output preset. The wide-temperature and three-proof design (resistant to moisture, salt spray, and mildew) ensures excellent protection performance
