QPP-0002 Quad Processor Pack Unit

Feature & Principle

It adopts 1oo2D synchronous dual-processor redundant design. Two processors run safety logic synchronously, hardware comparator checks calculation consistency, high diagnostic coverage rate. It collects field safety I/O signals, executes ESD and safety interlock programs. Dual modules can be configured for redundancy through dedicated synchronous bus, to ensure safety system continuous operation when single module fails.
