Structure & Components

• CPU Processing Unit: Responsible for executing safety logic and fault detection algorithms.
• Redundancy Module: Contains two CPUs with the same function internally, comparing operating status in real time.
• Communication Interface Board: Responsible for data exchange with upper computers and field devices (I/O modules).
• Power Supply Module: Ensures that the system can still maintain safety functions when there is power fluctuation or failure.
