The dual rack redundant CPU architecture is the core! Real time synchronization of data between the primary and backup CPUs, with a fault switching time of less than 100ms (imperceptible to the human eye), coupled with MRAM non-volatile memory, ensuring that the program is not lost during power outages. We have been operating stably for over 5 years in multiple multi million ton steel mills, with annual downtime approaching zero, safeguarding the core productivity of the enterprise.
Born specifically for strictness! The circuit board is coated with three anti paint and industrial grade wide temperature element devices, which have undergone -40 ℃ cold start and 70 ℃ high temperature aging tests. Batch application in northwest mining areas, coastal salt spray environments, high dust workshops and other scenarios, with a failure rate lower than the industry average of 50%, truly "able to withstand and rely on".
Smooth migration, worry free! We offer a "three-step worry free upgrade":
